The old-school white liberals have basically been lumped with Nazis by the blacktivists; who expects them to fund these attacks on themselves? For fifty years taxpayers have been doing the same, but they weren’t voluntary contributions.
I went to undergraduate and law school from 1961 through 1967. Most of my professors were libs.

Things have gone a long way down since then.
