@JMaxB The movement is pretty decentralized, but I'm assuming your talking about the national/international coordinating group. Their list of beliefs are here and I don't see any that claim that the only value this country was founded on was white supremacy.

What is true is that pretty much the entire white founding generation were white supremacists because that's pretty much all white people the world over believed at the time. Even most abolitionists never believed that African Americans were equal. That was certainly true in my faith tradition and we continue to struggle with that heritage.

One of the movement's points is that we can't deal with that legacy until we truly face it and own up to it. Think of how Germany is covered with plaques and markers about the Holocaust.

If you have a specific manifesto in mind, please share. I'd definitely like to look at it.
