Has anyone with psychiatry training ever commented on Scott Alexander's ideas?

I used to think that psychiatry-blogging was Scott Alexander's most useful/least harmful writing, because its his profession and an underserved topic. But he has his agenda to preach race pseudoscience and 1920s-type eugenics, and he has written in some ethical grey areas like stating a named friend's diagnosis and desired course of treatment. He is in a community where many people tell themselves that their substance use is medicinal and want proscriptions. Someone on SneerClub thinks he mixed up psychosis and schizophrenia in a recent post.

If you are in a registered profession like psychiatry, it can be dangerous to casually comment on your colleagues. Regardless, has anyone with relevant qualifications ever commented on his psychiatry blogging and whether it is a good representation of the state of knowledge?
