I find it interesting how racialised Christianity seems to have become in the US. It's as if something happened to it when it crossed the Atlantic, and it cross-fertilized with white supremacy. Seems there are lots of manifestations of that - things like the "Christian Identity Movement" that was the ancestor of much of the far-right, or the overlap between the push for Christianity in schools and segregation.
I reckon it has everything to do with the centrality of slavery to the early US economy.
In the US a lot of white Christians seemed to interpret their beliefs very differently to the likes of the Clapham Sect or John Brown, and other religiously-motivated abolitionists, instead morphing Christianity to be compatible with a system of slavery,
