Providing that an objective curriculum could be devised and standardized, would you be for or against teaching about (not preaching) religion including non-belief in public schools?
I completely agree with Dan Dennett in his book, Breaking the Spell, that religion should be dissected, probed, compared and analyzed scientifically in the schools. Once students are made aware of the commonalities of unfounded, non-scientific beliefs and fictions found in nearly all religions, they will be free to consider them as they would all other myths, legends, tales and fables.
Taught as history yes, dignify it with its own place no. Ideally.
Except to say that in the UK religion has always been on the curriculum, and it has all but destroyed it. I count the fact that it is on the school curriculum, as being one of the main reasons for religions decline in this country. So if you want to play tactically clever.
