In some sort of orientation before medical school I read of a summer program that prepared you for the transition from undergraduate to graduate school and prepared you for the coming courses. (BTW it was also FREE!) I stated an interest in this program and was told I could not participate because it was only for minorities.
I had a black friend in medical school that was ranting one day saying "they must think I am stupid, I don't need to cheat.....". I asked him what he was talking about, he said a few black instructors were at the black fraternity (forget what it was called) meeting giving the students current exams and other information about courses. The exams and special study materials were not only for their courses (the black instructors) but for many other courses as well. He and another black guy were very offended and did not take the info and quit the fraternity. Both stated that it was this sort of people (both the instructors and the students that participated) that made non minorities wonder if blacks actually earned their degree or position or if they were simply given it. This occurred at a state university in the southeast, I graduated in 2000 so I can just imagine what it is like now.
RE: Legal action, I agree with previous posts that being a white male you are considered the enemy and will always be the loser in race related cases. However, I think it also depends greatly on what state you are in. In Georgia you may have a chance, in Massachusetts I would say absolutely not.
