Your assessment of homeschooling is completely arse-about-face. Homeschooling brings the teacher-to-child ratio closer to 1:1 than you would ever get in a classroom; and supplementary to that parents tend to tailor their education to the nuances of the individual child.

Yes there are weirdo ideas amongst the odd homeschoolers but moronic unteaching at schools has catastrophically bad ideas -everywhere-. The idea that learning maths by practice "doesn't work" i.e. some retard application of that retard Piaget's retardard theory: https://www.origoeducation.ca/blog/piagetian-approach-to-teaching/ is endemic.

Even a cursory perusal of comparative studies shows a magnitude of superiority in results for homeschooling: https://www.thinkimpact.com/homeschooling-statistics/. Homeschooling is closer in form to the education forms seen in the mid-to-late middle ages, tutoring by parents, tutors (obviously), apprenticing to a trade, and squiring to another house: and the middle ages had the greatest advancement in technology and understanding of natural sciences in relation to the tools available for any period of history.

Face it: European Catholic / Orthodox Christian learning systems built the foundations every facet of -your- life that you think isn't suck. You just hate homeschooling, not because it is ineffective, but because you are a twisted and broken bigot, hating on a Christianity you know is right and isn't afraid to look at you straight on and show you that you are careening headfirst into the abyss. Because clearly when you were raised, nobody else did.
