Is literally everyone in the alt right a terrible person? You'd think there'd be at least one token decent one.
That's what differentiates the alt-right from Fascism. At least the Fascists had Rommel.
I think the distinctive feature of alt-right as a set of political and ethical principles is that it seems to encourage and even glorify attitudes that are degrading of
personal moral character: malice, greed, narcissism etc all seem to be positive to their eyes. The evils of fascism, by contrast, were rooted mainly in its precepts for how
society should be organized (and how such society would be better off without certain categories of people), but at the individual level, it at least paid lip service to universally recognized virtues such as self-sacrifice, dutifulness, bravery, etc.
Basically, the alt-right is what you get when you mix in old-school racism with Randian amoralism.
