I don’t understand this argument at all. Or, rather, I don’t understand its application to this particular situation. You repeatedly refer to “‘the alt-right,’ such as it exists.” The clear implication — notwithstanding your caveat that it does, in fact, exist — is that this movement is not fundamentally important. But at least two of Trump’s top advisers are closely linked to this movement: Steve Bannon explicitly through his own boasts about providing “a platform for the alt-right” and Michael Flynn implicitly through his repeated decisions to spread their views. I’m scratching my head over the idea that I’m not supposed to be deeply, deeply concerned about this. The fact that the alt-right attempts to exaggerate their importance doesn’t really respond to these concerns.
