I’m very slightly against banning him on Twitter, calling him a nazi, etc, because it gives him ammunition and an avenue to counter and actually appear reasonable in the eyes of a lot of people. A similar problem with the alt-right. His argument becomes “well, I’m demonstrably not a nazi, so look at how people on the opposite side of the spectrum sensationalise and misrepresent me” “the left-leaning social media corporations are intolerant of free speech”, etc, etc, and he appears somewhat balanced. Never mind how many of his actual views still conflate with xenophobia, Islamophobia, toxic nationalism, etc. It becomes a side point and most of his media appearances become about what he doesn’t represent than what he does.
I think the right and far-right are becoming savvy about what to downplay in order to appear reasonable and make the left look over-sensitive and against free speech, and it’s a slight of hand that we need to be very wary of. I’m not sure I’d ever have known who Milo Yiannopoulos was if he hadn’t been banned from Twitter, for example. He himself has called it the best thing that happened to his career
