I dunno they might know so little that they wouldn't quite understand the meaning of venerating Robert E. Lee.

Nah, they're very frequently racist as hell, but I wouldn't brand most of them as neo-confederates. I don't think there's enough drive to reinstitute slavery to brand them as such. I think most would settle for just making white people a legally elevated class. To be clear, that's still despicable, unacceptable, and a path towards the resurgence of neo-confederates, but that doesn't mean there can't be a distinction between the groups. More useful idiots to neo-confederates than actual members.
