It is not an observation unique to me that the current social-political-cultural trends that you see among young people bear all the hallmarks of a Evangelical-Puritan Great Awakening just with all the Bible stuff stripped out and replaced with radical politics and social justice. But the OS is the same and the country has been due for one.
And that’s down even to the current poly fad. All those previous revivals were accompanied by weird sex stuff too, all the way from mortifying the flesh up to and including free love type groups that were basically the “polycule.” And in those, too, the sex was secondary to the ideology, just like when you read these articles about folks doing poly but seemingly never actually getting down, it’s the least sexy thing you can imagine.
Not many of us are ready to acknowledge that a lot of those prior religious upheavals were absolutely progressive and not reactionary. It’s all even coming from the same place (New England and Mid-Atlantic elite circles, with parts of Cal as an outpost of the same group) and then trickling down and getting super enthusiastic once it hits the prole class. And Puritan revivals generally don’t encourage horizontal dancing.
