I don't want to get into the reasons this child of secular Jews, with no interest in patriarchal religions ended up in a Christian homeschooling group. I've talked about it elsewhere. It happened, and oh, it was my own personal Twilight Zone episode.
And yeah, mine was the only car in the parking lot at our enrichment classes without an anti-abortion bumper sticker. But that was only the beginning. From "creation science" (there is a whole segment of the homeschool/Christian school industry that caters to this market ) to full quiver families to those who practiced "courtship" instead of dating, it was a whole new - and damn scary - world.
But without a doubt, the most horrifying aspect, for me, was the embracing, by many of the group, of "Providential history".
