You guys have obviously never been married.

Because males were designed for hunting and dominance.

Hormones n' shit

Because testosterone!!!!! Bruh the jack off game is real

Well for one it has to do with the surges of testosterone in male animals. Another thing is that is most situations, the males assume the hunter or defender roles while females generally focus on maternal roles and caring for the family.

Testosterone? [spoiler]Than*[/spoiler]

Because in general, male animals in nature often fulfill the role of the alpha or the lease of the pack. When you establish yourself as the best, you're the one that gets to spread your seed. Not saying females can't be the dominant ones. It is just more common for the male to be above the females

Because we have stuff that hangs and it sometimes gets whacked by stuff while girls have everything inside and little chance of getting whacked there so we get angry when we get whacked.

Males aren't always the dominant sex in the animal kingdom. For example, females are much more dominant in black widow spiders and praying mantises.

Obviously because we have more testosterone

Land and women. That's why. However, in nature, you find that females tend to be more violent than males. In terms of territory and mating rights, the males usually fight until one gives up and leaves. Females, they fight to the death!! Usually because they are protecting a nest or already born young.

Testosterone

Because males used to hunt for animals, and females recolected other resources.

Tell that to a female red back spider

This article from Wikipedia might answer some aspects of your question. I took the liberty of copying and pasting the section of the article concerning gender below. Hope this might help clarify. [spoiler] [b][u]Gender[/b][/u] Gender plays an important role in human aggression.[1] There are multiple theories that seek to explain findings that males and females of the same species can have differing aggressive behaviors. However the conditions under which women and men differ in aggressiveness are not well understood.[41] In general, sexual dimorphism can be attributed to greater intraspecific competition in one sex, either between rivals for access to mates and/or to be chosen by mates. This may stem from the other gender being constrained by providing greater parental investment, in terms of factors such as gamete production, gestation, lactation, or upbringing of young. Although there is much variation in species, generally the more physically aggressive sex is the male, particularly in mammals. In species where parental care by both sexes is required, there tends to be less of a difference. When the female can leave the male to care for the offspring, then females may be the larger and more physically aggressive. Competitiveness despite parental investment has also been observed in some species.[42] A related factor is the rate at which males and females are able to mate again after producing offspring, and the basic principles of sexual selection are also influenced by ecological factors affecting the ways or extent to which one sex can compete for the other. The role of such factors in human evolution is controversial. The pattern of male and female aggression is argued to be consistent with evolved sexually-selected behavioral differences, while alternative or complimentary views emphasize conventional social roles stemming from physical evolved differences.[43] Aggression in women may have evolved to be, on average, less physically dangerous and more covert or indirect.[44][45] However, there are critiques for using animal behavior to explain human behavior. Especially in the application of evolutionary explanations to contemporary human behavior, including differences between the genders.[46] According to the 2015 International encyclopedia of the social and behavioral sciences, sex differences in aggression is one of the most robust and oldest findings in psychology.[47] Past meta-analyses in the encyclopedia found males regardless of age engaged in more physical and verbal aggression while small effect for females engaging in more indirect aggression such as rumor spreading or gossiping.[47] It also found males tend to engage in more unprovoked aggression at higher frequency than females.[47] This analysis also conforms with the Oxford Handbook of Evolutionary Psychology which reviewed past analysis which found men to use more verbal and physical aggression with the difference being greater in the physical type.[48] There are more recent findings that show that differences in male and female aggression appear at about two years of age, though the differences in aggression are more consistent in middle-aged children and adolescence. Tremblay, Japel and Pérusse (1999) asserted that physically aggressive behaviors such as kicking, biting and hitting are age-typical expressions of innate and spontaneous reactions to biological drives such as anger, hunger, and affiliation.[49] Girls' relational aggression, meaning non-physical or indirect, tends to increase after age two while physical aggression decreases. There was no significant difference in aggression between males and females before two years of age.[50] A possible explanation for this could be that girls develop language skills more quickly than boys, therefore they have better ways of verbalizing their wants and needs. They are more likely to use communication when trying to retrieve a toy with the words "Ask nicely" or "Say please."[51] According to the journal of Aggressive Behavior, analysis across 9 countries found boy reported more in the use of physical aggression.[50] At the same time no consistent sex differences emerged within relational aggression.[50] It has been found that girls are more likely than boys to use reactive aggression and then retract, but boys are more likely to increase rather than to retract their aggression after their first reaction. Studies show girls' aggressive tactics included gossip, ostracism, breaking confidences, and criticism of a victim's clothing, appearance, or personality, whereas boys engage in aggression that involves a direct physical and/or verbal assault.[52] This could be due to the fact that girls' frontal lobes develop earlier than boys, allowing them to self-restrain.[51] One factor that shows insignificant differences between male and female aggression is in sports. In sports, the rate of aggression in both contact and non-contact sports is relatively equal. Since the establishment of Title IX, female sports have increased in competitiveness and importance, which could contribute to the evening of aggression and the "need to win" attitude between both sexes. Among sex differences found in adult sports were that females have a higher scale of indirect hostility while men have a higher scale of assault.[53] Another difference found is that men have up to 20 times higher levels of testosterone than women. Some studies suggest that romantic involvement in adolescence decreases aggression in males and females, but decreases at a higher rate in females. Females will seem more desirable to their mate if they fit in with society and females that are aggressive do not usually fit well in society, they can often be viewed as antisocial. Female aggression is not considered the norm in society and going against the norm can sometimes prevent one from getting a mate.[54] However, studies have shown that an increasing number of women are getting arrested for domestic violence charges. In many states, women now account for a quarter to a third of all domestic violence arrests, up from less than 10 percent a decade ago. The new statistics reflect a reality documented in research: women are perpetrators as well as victims of family violence.[55] However, another equally possible explanation is a case of improved diagnostics: it has become more acceptable for men to report female domestic violence to the authorities while at the same time actual female domestic violence has not increased at all. This can be the case when men have become less ashamed of reporting female violence against them, therefore an increasing number of women are arrested, although the actual number of violent women remains the same. Also, males in competitive sports are often advised by their coaches not to be in intimate relationships based on the premises that they become more docile and less aggressive during an athletic event. The circumstances in which males and females experience aggression are also different. A study showed that social anxiety and stress was positively correlated with aggression in males, meaning as stress and social anxiety increases so does aggression. Furthermore, a male with higher social skills has a lower rate of aggressive behavior than a male with lower social skills. In females, higher rates of aggression were only correlated with higher rates of stress. Other than biological factors that contribute to aggression there are physical factors are well.[56] Regarding sexual dimorphism, humans fall into an intermediate group with moderate sex differences in body size but relatively large testes. This is a typical pattern of primates where several males and females live together in a group and the male faces an intermediate amount of challenges from other males compared to exclusive polygyny and monogamy but frequent sperm competition.[57] Evolutionary psychology and sociobiology have also discussed and produced theories for some specific forms of male aggression such as sociobiological theories of -blam!- and theories regarding the Cinderella effect. Another evolutionary theory explaining gender differences in aggression is the Male Warrior hypothesis, which explains that males have psychologically evolved for intergroup aggression in order to gain access to mates, resources, territory and status.[34][35][/spoiler]
