Similar situation here. I was raised home schooled for all of my education. Got a GED, good score on the ACT, got a 4.0 in the community college where I got an associates degree. The problem is parents who homeschool because they don't want their kids to turn "woke" or be "converted" by exposure to the fact that non-straight, non-cis people exist. A lot of the time, the emphasis is only on indoctrination, and there is little or no actual education involved.
I have been to homeschool conferences - there are some good resources there, and a LOT of really pretty awful stuff like this article mentioned. People like the author are so incredibly impactful, even if they don't realize it. They may never see results but those seeds matter. Even if the parents don't get it, the kids will.
At a conference last year, there was a speaker talking about parenting difficult children (Kirk Martin with Celebrate Calm). He was presenting very much a solid gentle parenting approach (though he didn't call it that) that is very contrary to the culture of a lot of homeschool groups. He spent a lot of time unpacking his experiences as someone who grew up with really strict physical discipline, the impact it had on him, his experience being a parent - kind of leading people on a journey from where they might be to where they should be as parents.
He also spent a bit of his talk on how the Bible doesn't teach us to raise our kids to fight in a culture war and just really pretty clearly calling out a lot of the toxic far right christian-nationalist talking points. Sure he made a lot of people uncomfortable, but those thoughts will stick with them.
After his talk he was spent over an hour talking with people outside of the conference room answering questions. His next talk was packed as well.
Anyway, all that to say - I know it can take a lot out of someone to deal with people in those environments, but it is absolutely impactful and so desperately needed.
