Yes. This is one reason I bothered to comment. Psychiatrists who step into the public space bear a particular obligation both to advocate for our patients and to push back against misinformation.
It's a fairly ungenerous read that would lead you to imply he's failing in some professional obligation. It's like discussing murder - how often do you need to state that you think murder is A Very Bad Thing? Do oncologists need to talk about how bad cancer is every time that they write about it in a public space? Eh.
They would if a surprisingly large portion of the public believed cancer didn't actually exist.
