I've got nothing against Muslims, or Jews, or Catholics etc as such, just against the a$$holes who do terrible things that happen to belong to those groups.
What if some of these "a$$holes" were motivated by the religion in which they were believing in? For example, we have brainwashed Muslims blowing up in pubs and nightclubs, so that they could get 72 virgins and rivers of alcohol in the heaven. Now you need to admit that religion is playing a major role here.
