Atheism is quite western. People who don't believe Hinduism or whatever in countries like India for eg don't seem to have a complex with thinking they know anything more than someone who believes different. Atheism in its general media and public depiction is just the opposite of Christianity. They have their beliefs etc (or lack there of) and like ye old Christians try to shove it down others throats. Equally arrogant, equally lacking in intellect and most importantly completely disconnected from a self spiritual realization thus making it all completely disjointed and meaningless much like trying to argue a theory about a black hole. Yeah you might be passionate about whatever but it doesn't mean much at the end of the day. That my friends is called the ego's defense. And if u need to defend what you believe it might prompt people to wonder whether you really believe it... Hello infinite arguments about religion etc
