Here's an idea for a different approach to combating the "teach the controversy" mob. Why don't we try to introduce "teach the controversy" into religious classes? Surely religious beliefs themselves are more controversial than evolution or climate change. Let's insist on introducing such ideas into religious teaching!
If they say "God said blah", then they should also have to teach the other side, that maybe God didn't say that, or doesn't even exist, and that there's no consensus about this. Throw in some science and history showing how the bible came into being, morphed over time, and point out some factual errors and self-contradictions.
Even teaching comparative religion seems to be along the lines of "some people believe this, and some people believe that", while still being careful not to question any belief. I'd like to see the next generation being taught what science really tells us about religion.
Maybe by trying to get science into religious classes they may see the trouble they're in and back down from introducing their religion into science classes.
On the other hand it may just antagonise them!
What do you think?
