Minor nitpick: it was time to start worrying about Christian nationalism over twenty years ago. They’ve been trying to legitimize Christian nationalism since at least the founding of the “Moral Majority” when I was a boy. I’ve been trying to sound the alarm about Dominionism and Christian nationalism since the second Bush administration.
But if you’re late to the game, fine. The second best time to start worrying about Christian nationalism is now.
That’s the most explicitly written stance on religion for the US I’ve heard of, but I’m not sure these CN dummies care whatsoever about what was written as a shipping and anti-piracy deal with Libya, which was also written in Arabic.
