There is a place for religion in schools.
It's in the social studies class alongside all other religions, myths, creation stories, fairytales and other ideas that have passed their use-by dates.
My main issue with religion in schools is that it doesn't teach about all religions, only one, that of Christianity, and it's beyond me how a bunch of Iron Age farmers can offer anything to a modern society.
Just look at the world around us right now and leaf through a history book if you need any proof of how religion has "advanced" society.
Do they teach these kids about the horrors of the Inquisition? The burning of so-called witches? Christian pogroms against Jews?
