That American Atheist described in the op seems less like a cult person and seems more like regular asshole to me. Just don't be like that. You can be an idiot while being christian, atheist or Buddhist.
You can always keep it in your own lands but we in Europe don't care for religion no more..
Religious people telling us how we should live .. RELIGIOUS FREAK ..Gods are over ..
No arguments for religion..I.E No provable points.. so you hit out because you get frustrated because you get proved wrong so much we atheist have all the fun and you religious get angry ..You got no provable points so you end up looking like IDIOTS ..
This is the point we are sick of religion.. Always 1 religion starting some shit somewhere in the world..
Islam now scientology tomorrow..Well am afraid all religions will be looked and studied and people will make there own minds up instead of being forced to believe in poppycock..And as time goes on because of the internet the future children will look at religion like we look at witches today..
