This is more of a note than a fully hashed out idea, but I think there is something to the fact that the “tribe” of college-educated adults and especially college-educated parents is where what remains of functional parenting culture lies in America among American-born Americans. It’s the college-educated who hook each other up with nanny shares, allowing them genuinely flexible childcare that pays a good wage to the nanny while none of them ever pay more than center-based daycare costs per family. It’s the college educated who can still find college-educated young women willing to barter and be live-in childcare for a gap year or two. Who make social events mixed-age, and welcoming to children and their parents. There is a loyalty and support base there that even crosses political boundaries. But of course, both parents have to be college-educated.
Thus, when the political rubber hits the road, conservatives are more loyal to their real tribe of college-educated types than their supposed tribe of conservatives, Christians or conservative Christians. I’ve seen way too many non-Christian college educateds serve as enforcers of progressive stuff by assuring college educated Christians that so long as they agree with some progressive thing (obviously being frothy about how evil Trump is would be a recent example) they’re “sane, sensible Christians” and thus acceptably human and allowed to retain access to a fairly vast social network.
And why shouldn’t they scrabble for the attentions of fellow college-goers? Completing a BA/BSc or more has a shared vocabulary and world of experiences that crosses the same kinds of political and ethnic lines that church or parish (sometimes) used to. Being cut off from a complete culture with its own traditions and lore, and of course, support in real terms like showing up to watch your kids with ten minutes’ notice, it’s easy to see why Christians end up choosing to go along with tons of progressive cant to maintain those bonds and access to those resources.
