100%. It’s unfortunate that more attention isn’t paid to the “Southern Strategy” - started by Nixon but honed and perfected by Reagan. It was basically a massive counter-revolution where whites hated that black Americans were granted civil rights, marginally improved economic standing, and more broadly there’s at least an attempt to put whites and blacks on an equal footing. This sort of white supremacy was sort of laundered through evangelical Christianity but yes, it’s whiteness first. The “Moral Majority” began as movement to fight the government from removing the tax-exempt status for private Christian schools that practiced racial segregation, for example. While white evangelical Christianity does predate the reaction to the Civil Rights movement, I think it’s fair to say that this white supremacy is the foundation for modern white evangelicalism.
