I think a lot of parents are home schooling to get their kids out of the classrooms filled with green/blue dyed hair teachers who are more concerned with indoctrination than education.
The pandemic opened A LOT of peoples' collective eyes as to what was really going on in classrooms that parents didn't have a clue about.
Encouragement of trans....grade school kids exposed to information on anal sex and how a boy can give a blow job were the most egregious examples....but just sets values that didn't set with what parents in general in the US want to impart to their kids.
the US population is generally middle of the road and you screeching green haired instructor is pushing stuff from the far left in many cases.
Parent's saw this and are putting a stop to it.
Frankly I can't blame them.
