Err... that's really general... and what's wrong with the Brian guy from Temple?? He was really helpful and chill about everything!!! Luckily I'm not white, so I'm not offended (but I sense a huge backlash waiting for you). For whatever reasons (paranoia etc.) people will always be racist (Hell, I had racist profs), but one single race should not be singled out as being racist..
I don't think you should hate on a particular race, since you will have to SERVE everyone when you're a dentist! Anyway, were you listening to Kanye West when you decided to post this *Recall his outburst during the Katrina telethon*??
