He's also a non-metaphorical Nazi.
The advent of the Internet has truly watered down the term "Nazi" to be almost a caricature. This administration has caused it to be watered down even more.
Are members of the "Alt-White" nazis? For the most part, no. They don't necessary subscribe to nazism, totaliarism, or authoritarianism. They're racists, bigots, misogynists, and otherwise sick excuses for humans...but not they're nazis.
Richard Spencer? Close enough. Steve Bannon? No, he's just a worthless, racist piece of shit, but he's not an nazi. This Gorka fucker? An actual Nazi.
