> 2) Fear of school shootings.

I would add:

3) Fear of fear of school shootings.

The active shooter drills and other security measures that American kids go through in some schools are positively dystopian. Even if the chances of a school shooting are statistically very low, the measures put in place to prevent them are probably not good for kids' psychological well being.

I have some friends who are Christian but left wing (their kids would come over to play and draw pictures about helping poor people.) The dad teaches CS at a small Catholic college, mom stayed home and educated their kids.

The "disgust over woke issues" existed in some form 30 years ago when people were homeschooling but it had not hardened into the constellation it is in now. Back then you could get folks like that to talk articulately about how they disagreed with secular values, introduce a word like "woke" and now people talk past each other, at best, if they talk at all.
