It's the people, stupid, to paraphrase an American election campaign. Lot's of crazies believing in the supremacy of their religion, (no different to white supremacists) who go round causing a lot of human kinds problems.
It is not so much the "God", as the idiots that shove it in everyone's face and who don't know how to shut up. We don't hate "God", because how do you hate something that doesn't exist? Do you hate unicorns? Or dragons? Then how can we hate something that doesn't exist?
