Most Ignant thing you've heard in class/anywhere

I think one of the most ignorant things I've heard so far in college was in my African-American Studies class. We were discussing the many ways that racism shows up in our daily lives when out of the blue, this White classmate blurts out, "um...I think that if I was Black, I'd wanna be a lighter Black.....at least they're more attractive in the prostituting world." All I remember after that comment was the professor giving her the dirty look and asking her to leave the classroom. That classmate never came back either
