You can't talk about depression without someone saying some shit like "well, based on nothing, I think that all doctors psychologists and neurosciencists are wrong about everything"
And than you say "that seems unwise"
And then they say "WOW, DOCTORS HAVE BEEN WRONG IN THE PAST"

Yes, true, doctors make all sorts of mistakes.
That doesn't mean you should reflexively assume that all science and data regarding mental health is critically flawed in some way that they all missed but you intuited from nowhere.

People recycle all sorts of old ignorance through some superficially anti-capitalist filter and think they've made a new point.

Here they come I guess.
