Milo Y. makes fun of feminists, and doesn't want Muslims to overrun his country, so he is a "neo-nazi". I haven't seen him advocate violence, and he says he believes most Muslims are nice, fine people. While he is snarky, and often mean, to call him a neo-nazi, or white supremacist is nonsense.
Mostly he points out contradictions from Progressives.
