That's.... utterly unrelated to almost any point I've made, I would never claim that "all" teachers are anything aside from teachers. I'd argue that *most* are underpaid, etc, etc - but I'm also utterly unconvinced by a single, unproven example.
I suppose you are trying to argue that parents are a better source for this sort of thing? Why? What, to you, distinguishes what a parent should teach and what a teacher should teach? Is your position fundamentally anti-public education? I can sympathize with you, but the fact of the matter is that too many parents are bigoted against LGBTQIA+ people to properly teach it - as in - according to the science. While this isn't unique to parents, teachers can be regulated and told to not teach stuff that isn't true (which, is also a problem, but that's a whole other thing).
One more question, before I go, if you decide what each category of person should teach (teachers and parents), what is your proof that this should be the case? And don't use another anecdote which we can't verify, please present some sort of empirical basis for your claim, or an argument which philosophically demands that to be the case (for example: If P, then Q - > P -> Therefore Q).
