I'll explain. People who are around* guns are more likely to die than people who are not (especially from suicide, interestingly). Thus, people who do not see guns as having an inherent danger to them are more likely to have themselves wiped from the gene pool. * in case you're too thick like most of the other people here, this is referring to the normal use of a firearm by a person (where normal refers to how they would regularly use it)
