When I started pinging this list out, the reasons for homeschooling were mundane things like kids getting bullied for their lunch money and grade inflation or unfair grading practices or introduction of sex ed teaching at all.
Now it's come to this. Kids being killed and maimed for life and banned from all sports because they refuse to compete in a competition when girls are set up to be the losers because guys are playing in their sports.
I remember the hue and cry when girls wanted to play on boys teams and how dangerous it was and sexes shouldn't be playing together, and now they being required to shower together.
Evil rules us.
One of the saints told of waking up and seeing a demon or the devil hanging over him. He said “oh, it’s only you” and rolled over back to sleep.
Evil can rule us only if we let it.
That said, countless parents need to see what’s happening, and take charge. Even Jesus at times saw the rabble and slipped out the back.
There is a greater imperative than “socialization.” The irony, as you note, is the immediate challenge when “outing yourself” as a HSer was “what about socialization?” NOW, socialization is one of the WORST dimensions of public education.
