I've also been reading SSC for a long time. I'm sad, but honestly, who's surprised? I mean, he defended Steven Hsu the other day for being on the wrong side of the whole "race/IQ differences" thing, despite having written probably a dozen essays over the years about the phenomenon of prominent people losing their jobs for being on the wrong side of the race/IQ differences thing.
Scott's had a pretty amazing run of being able to write edgy-enough-to-possibly-get-you-cancelled essays on the internet without getting cancelled, and on a personal level I've found him to be extremely kind and thoughtful and I wish this weren't happening to him, but at the same time it seems as inevitable as the flooding of a house built on low ground.
