The professor looks awfully white to me.
According to liberals—and especially the ones in academia—white isn’t merely a color. It’s an attitude and identifier. If you believe in: being productive; willing to work hard; to be independent and not a burden to others; resent grifters and mooches; and a color-blind society/ALL lives matter—then (to liberals) you’re “white” and you are “racist/supremacist” against “non-whites.”
This is how men and women like Ben Carson, Dinesh D’Souza, Michelle Malkin, and others, can be called “racist” and “white supremacist” by liberals. It is most effective when they charge that against a conservative to an audience that probably doesn’t know who they are.
Maybe she identifies as black....
