I’m not familiar with Scott Alexander or his blog, but here’s a post of his that’s well worth reading. It’s an in-depth attempt to evaluate some of the worst racism charges against Trump, and to estimate how numerous the supporters of white supremacist groups really are in this country (those are two separate issues, by the way).
Alexander is apparently not a Trump guy; he’s a psychiatrist who writes anonymously and is concerned about some of his patients who have become suicidally fearful since the Trump victory.
Alexander’s post is very long. I’m not in agreement with all of it, but it’s well worth reading. I think that white supremacist support for Trump is important and needs to be watched carefully. I don’t think the numbers are as small as Alexander seems to think, but both of us are merely estimating and I’ve consistently said I do not know, although these people are at least potentially dangerous. That said, I agree with Alexander that at the moment there’s no reason for alarm.
I also have said that one of the things that was a red flag for me with the Trump campaign in general was the failure of Breitbart et al to ban overtly racist or anti-Semitic comments from their sites. It’s easy enough to do it (believe me, I know) and it wasn’t done, which was a choice. You might say it was a libertarian choice, and I say “perhaps.” But it’s one of the things that has fueled the fires of the “Racism!” charges against Trump and his supporters—although that charge would be leveled anyway at Trump. It’s been leveled at almost every Republican on earth for quite some time.
