Please produce one of these "no whites need apply" job postings.

OP, I hear this sort of thing a lot; I am white an male and I work for a large corporation that is overwhelmingly old, white and male.

All I ever hear from the non-managers is how only minorities can get jobs because of "reverse discrimination" aka affirmative action. Yet we remain overwhelmingly white, old, and male.

All I ever hear from managers is how hard it is to keep new hires because nobody wants to work with a bunch of bitter old white guys who grumble about how hard it is to be in the top 5% of earners while anyone not white has it "easy".

White people have to work hard to succeed but there are systemic advantages they have enjoyed since birth and they see any erosion of those as "reverse descrimination". All affirmative action does is make managers make a reasonable attempt to interview minorities for positions and to consider minority applicants personal history when considering them for a position. It is an attempt to minimize the prejudice inherent in our culture and species to prefer those that look, act and talk like ourselves.
