I think onager's point is a good one, because if you are not going to discuss obscure worlds views in the classroom, why discuss the most popular one? Without "gatekeeping", what's to stop any old rubbish being discussed? You have to draw the line somewhere.
The "some people believe" approach works to an extent. But why are more likely to say of, for example, David Icke's lizards, or Flat-Earthers, "well, some people believe this but frankly they are off their rockers and it's a crock of shit", whereas we are supposed to say of the farrago of exaggeration and hagiography in the Bible that it should be treated with deference and respect? They both seem to come from the same place - woo-world.

I think that's a bit disingenuous. Even if we keep saying the first - which is something of a rephrasing, but never mind, I'm sure I'll come back to it - then it doesn't necessarily follow that we say the second. Scientists I've seen in the media like Dennett, Harris and Dawkins are extraordinarily courteous to religion, in that they give it the platform to debate and the opportunity to back its theories up with evidence. None is ever forthcoming.
They are all far more polite than I'd ever be, and to be honest I don't know quite how these guys do it, patiently stating the logic of their position again and again in the face of superstitious ignorance. Even Dawkins, with his "spiky" debating style, is no more acerbic than he'd be to any scientific colleague. It's debate, chellenging, querying, having its authority questioned. The one thing religion hasn't had to a great extent in recent centuries. And now it's happening, now that people dare question the church in numbers, and with authority, for the first time in generations, the church is scared of the way the world appears to be slipping from its grasp.
And given that the religious have held enormous power - political and economic power, most importantly - for so long, who, frankly, can blame them?
