In reply to thread:
Give Robert a break. Be excellent - for two reasons.
Firstly in the spirit of the OP's post.
Secondly because, actually, kids have brains, and can figure out stuff for themselves. If there is any kind of decent relationship going on in his classroom, I would expect a fair bit of 'push-back' on a remark like that, and a chance of a good discussion thereafter, if properly led.
I get irritated by the anti-religion brigade et al, who assume our children can be brainwashed by adults with the wrong views, and instead, want to brainwash them with their right views. Please give the children a chance to decide for themselves. That is what education is.
