Can confirm. I went to a mostly black college and one of my English professors was African (no shit, it wasn't even his native language, but fair play, he spoke it better than most of the students). He absolutely hated the African American students and during private office hours would vent his frustration to me and a few other students who didn't behave the way they did. Me and the other white guy in the class were his favorite students (though he did thing we were brothers, lol), simply because we did the work and didn't just talk through class and be completely ignorant to the professor.
