Derec, AA removed giving preferential treatment to white males. It made it illegal to discriminate in the basis of sex, race, religion and national origins. Women, non-Christians and persons of color were finally allowed to apply for admissions and jobs previously denied them because of their race, gender, religion and national origins.
The rest is simply racist backlash because some people are too insecure to believe that white makes can actually compete without the centuries of preferential treatment they received.
Calling it racist backlash doesn't make it so.
My exhibit A on this: I was a lab assistant in the computer labs on campus. We had this one Hispanic outreach group that used the lab. They were very different than the regular students. The behavior of the
teachers for it would have gotten them thrown out if it wasn't for the racial aspect. The students simply weren't college material--ended up being more work for us despite the class having its own assistants. (And the main one managed to corrupt a word processor document. It happened on occasion, during some slow time I worked out a recovery method that turned the corrupted structures into a few lines of crap at the top of an otherwise text file. Vastly beyond the expectations of the job and I only taught it to a few of the most technically competent people because it would be very easy to corrupt the whole floppy with an errant letter. Her document was of absolutely maximum length, the crap at the top pushed off an equivalent amount from the end--and she tried to get me fired over losing the lines from the end. I clearly did that because she wasn't white.)
