> HR departments [...] believe that having white skin is a sin

Can we just stop? This is a meme, it's clearly never been true. It's extrapolating from a bunch of intemperate stuff said by oddball losers (yes, often in academic environments which encourage out-of-the-box thinking and speech[1]) to tar a bunch of extremely bland policies enacted by HR and hiring managers (to ensure that their masters don't get sued) with an ideological brush.

We people with "white skin" are very clearly doing just fine in the job market.
