Pity that you haven't bothered to find out what it means before deciding that you hate it, because you clearly don't understand it.
Well I do know about it and I hate the phrase and the concept. First, the phrase is bad on the basis that it defends discrimination, or at least portrays that a preference of a gender, race or possibly health over someone of the same experience and education is in some way levelling the playing field. It's not, it's just creating and hiding a very specific form of discrimination among a class of people who have no remit and have no ability to do anything about it: caucasian men.
If there is to be true equality then it has to be on the basis of "blindness". There is no doubt that there has been significant (and still is) inequality, but you cannot fast-track this by introducing a different form of discrimination.
So the term is rubbish and the concept is rubbish.
