I do believe God exist, but religions have always been used as an excuse to do all sorts of shit, so world might be better off without organized religions. Not to despise the religious organizations that do help people - those do exist too and they are great.
Anyway those who use religion as a reason to rob money, judge, hurt, attack, rape, kill... do they really think God wants them to do that? Like God is some shithead? I don't think they even believe in God.
