The current PC definition is ludicrous being Racism: What non PC white people think and say and do in regards to anything at all.
Liberals live in a world free of the constraints of cause and effect. In liberal land, it is simultaneously necessary to reduce the entrance requirement for a certain segment of the population because they are less qualified, but racist to suggest that entrants from that segment might be less qualified than entrants from other segments. The notion that the very act of reducing entrance requirements is almost guaranteed to reduce the average quality of applicants somehow escapes them.
