Incidentally, there’s a simple solution to the problem of teaching the history and literature of religions in public schools without “accidentally” tipping over into, you know, proselytizing: Have atheists teach the classes. Yes, that will go over swell, I know. I’m just saying.
He’s right, it would never fly, but I have a suggestion that might make it work. Two rules:
The person teaching the course may not at any time or in any way, even indirectly, discuss his or her own religion.
All discussion of any religion must be value-neutral, that is, you can’t talk about what’s “good” or “bad”, just state the historical and doctrinal facts.
Since most teachers are going to be Christian, that means Christianity would get short shrift, which isn’t appropriate…but the obvious solution there is to have guest lecturers. Invite the local Muslim or Buddhist in to summarize Christianity from his or her perspective. That alone, of course, would guarantee that the instructor couldn’t be some raving fundie—imagine a David Paszkiewicz having to sit quietly at the back of the room while a Dawkins-like atheist or a Muslim like Keith Ellison explained Christianity to the class.
