> I bristle a little bit at the characterization of "antivax, sovereign citizen, fear of radio frequencies, or extreme religion" as intellectual abuse.

Oh, bristle away! I accept I am being contentious. But I grew up with several friends (even at a mainstream school) whose parents were in these categories (not so much fear of RF, that’s newer).

Some of this stuff takes a hell of a lot of unpicking in later life; I know two adults who grew up in a common-enough minority religion who consider what they were taught to think to be profoundly damaging to their long-term intellectual, social and mental wellbeing.

To pick up on one thing to agree with: I think it’s enormously important for children to have exposure to professional teachers. To people who know how teaching works, how to adapt it, how to moderate and meta-moderate learning.
