When I was in law school, we didn't have a lot of black people in my class but they were all super smart. One guy was a medical doctor already before he started (not a dentist, and in one of the top 20 law schools in this great land of ours).
So, umm ... yeah. That's totally reprehensible, mostly because it's totally false. Or maybe her racism worked its way into her grading of her students, which is even worse. Black law students tend to get the same grades as white law students, in a fair environment.
I went to Georgetown for undergrad, and I had to take classes in religion to graduate, and I got a poor grade (a C) once because the final exam was a one-on-one session with the professor, who was a priest wearing a collar. I stuck to my guns that I knew the material cold but I was an agnostic and I was still going to be an agnostic when I walked out of his office, so he gave me a C. It's an experience that angers me every time I think about it.
So as someone who was discriminated against because of my (lack of) religion, I can only imagine the feelings of someone who was discriminated against because of their race.
My blood is boiling right about now. I better go do Musical Asskicking and work it out.
