Well, the survey information they’re basing that on does not indicate white supremacist views. For example, the fact that they don’t believe in white privilege probably comes from the fact that they’re working-class households in places like the rust belt.
Of course I’m committing the cardinal sin again of using the R word without stating in which sense. I’m using “racist” in the casual “holds racist views” sense, so a much larger group than white supremacists, but smaller than the “unknowingly perpetuates racism” sense. When you said racists voted 99% Republican, I made the assumption you were using it in that sense and I responded in kind.
I believed both of our statements were about these casual racists in general, I just added that it could even extend to a few white supremacists too. If it turned out you were just talking about white supremacists the whole time, mea culpa, that would be a small group, and your 99% number was conservative IMO. In the sense I’m using the word, the survey results seem to back me up. It definitely shows racists, in the broader but not all-encompassing sense of the word, voted for Obama, and then switched to Trump more strongly than any other measured demographic. And I wouldn’t be surprised to find a white supremacist or two in there too – but there’s no evidence on that either way.
