I think most of the middle east, large swathes of Africa, considerable parts of Asia, chunks of North America, and Infact almost anywhere in the world where people of a religion disagree with people of another religion/sect/non-religious, there is varying degrees of harm - all the way from disparagement to murder/genocide.Anyway, we got there in the end, and to be fair the god botherers aren't doing too much harm these days, they're kind of irrelevant.
I think we are a very long way from being able to declare that religion is harmless.
