There seems to me, looking at all of this US hyperpartisan nonsense as an outsider, to be quite a bit of difference between the frothy Gab/Parler/etc contingent and an average median republican (who I don't really imagine spends a ton of time on niche social media).
It's because conservatives see rhetoric about "white supremacy" as a weak man argument used against them. They don't believe themselves to be white supremacists. It's kind of like centrist Democrats being annoyed when conservatives call them socialists and communists. To see this as telling on themselves in this context is a bit like McCarthy saying only a communist would deny being a communist.
