One problem with your post is that it is necessarily underpinned by the assumption that parents cannot be trusted to act in the best interest of their child, and actually that they will go out of their way to pay for their child to be abused.
That is because you have retained all the motives (“abuse,” “recruitment,” “sexualizing,” and “advocacy”) that have been supplied under the framework in which you say this is a nefarious endeavor by the leftist teacher’s union school board cabal, or whatever, and applied them to a free market driven by parents’ choices.
That’s absurd. Sure there will be instances of parents abusing their children, but once you start assuming that parents writ large can’t be trusted to recognize abuse or decide what’s best for their child then you’re engaging in the same failed regime, you’ve just substituted your own cultural norms and preferences for the leftist teachers’ union school board cabal.
That’s why I say that when the decision is left to the parent, there should be a barely rebuttable presumption that they are acting in the best interest of the child and the market will do what markets do.
If you’re saying that schools will “abuse” children without the parent’s consent, then I really don’t have a problem with a law that prohibits that. In fact, I believe they already exist.
No, I trust that most overwhelmingly will, and that private schooling parents are likely as unaware of inappropriate and harmful material as public school parents. With private schools being such a paucity of total schools, I haven't looked into whether it is occurring to the same degree. I do know that NAIS, accreditor of private schools, has an instructional program supporting transgenderism in PK-8 and I've seen the same materials being used in public school systems nationally. The national associations, state DOEs, school systems and teachers who openly or confidentially admit they'll ignore laws, have a uniformity in what they relabel CRT, 1619, alt-sex curricula - terms like Social Emotional Learning (SEL) or Diversity, Equity, Inclusion (DEI). The same shite PK-12 books show up in schools nationally; mods deleted my sampling post from elementary school books as too graphic for this forum. I've posted several examples - and read numerous others - of school systems taking children into their counseling, making a decision the boy is a girl/vice versa, and from there addressing the child as another gender and name and concealing it from parents.
It's hardly coincidence the same materials, terms, and training programs have been replicated in school systems nationally when one considers the NEA and AFT donate to leftist candidates to virtual exclusion, and have taken hard lines teaching collectivism. Hardly coincidence that four generations of progressive corruption of education has also resulted in a congress infested with socialist sympathetics, and a majority Dem voting populace that favors socialism. And they aren't exactly hiding the agenda anymore; it's open war, the declaration being NASB conspiring with the WH, DOE, and DOJ to pursue parents as domestic terrorists. I see how law is being used to politically vilify parents, not assist them in preventing abuse of their children.
Education has a roughly 80-85/15-20 split between progressive/conservative thought, and higher at the admin level. It's absurd to conclude the product isn't leftist.
A nefarious education cabal...personally, I like it, but since coming out they're not a secret. I'd use 'cartel'.
