"Diversity" in practice means aiming for fewer white men in positions of authority.

What it truly means is “let’s aim for fewer white men in positions of authority,” which would be a fine idea if race and sex were reasonable criteria by which to judge applicants, and if it wasn’t motivated by a broad set of “progressive” beliefs, which include the idea that we live in an oppressive patriarchy and that men who work now should be required to step back so that a litany of hypothetical, indefinable and prejudicial historical wrongs might be righted (this even though those who do the righting weren’t those who committed the prejudicial crimes, so to speak, and those who benefit not those who were the victims).
