We never purged anyone. I have no idea what my colleagues' political affiliation is, though in some cases I could guess. But Republicans have politicized one academic discipline after another, and cannot really expect to do that and retain the allegiance of actual experts in those fields.

I won't even bother with Brooks' screed against identity politics. Which party presently thinks that people's ethnic, religious, or gender identity is the only important thing about us? Not Democrats.
