Reverse discrimination is just reactionary discrimination that hasn't become mainstream yet.

There's a good Dr Seuss story about a guy that comes into town with a machine that stamps a star on your chest. A few people get it and think they're better than everyone else until everyone gets the star and the fashion becomes not having the star, and the story oscillates between star and no-star until everyone's out of money and the huckster with the star/no-star machine moves onto the next town.

Discrimination of all kinds is and has always been about mobilizing people against each other for the sake of accumulating power/money/resources.

Discrimination... discrimination never changes.
