Atheists believe that almost all/all RELIGIONS are delusional, and that atheists are the only sane ones?

it depends, i'm an atheist, but I don't promote that in any way, unless I have someone giving me **** about it,v then I will defend my lack of faith, but there are groups out there, Like the rational response squad that say they're atheists and secular humanists, and the only thing they're really doing is substituting their former religion with secular humanism...I guess people like that make atheism, and atheists, look bad, because atheism is a lack of a belief in a deity, there is no reason for atheists to organize ( other than, say, support groups), and in turn no reason for atheists to attack any other belief...I'm not saying I won't laugh at a ridiculous notion or belief, or that I won;t question it, but for the most part I keep my lack of belief to my self, like I wish others to do with their religious convictions
