I agree with all this.

I guess when I think of science, I think of a machine that sucks up judgments from biased humans, and somehow spits out results that converge on the truth. Of course, this convergence happens faster when the humans do their best to be less biased in advance. And the convergence can be reversed if the biased humans are bad enough.

So I'm willing to tolerate a lot of trash criticism if it means that a little good criticism also gets through. Maybe in the face of the current political environment, I should be less tolerant of trash criticism; not sure.
