Visible minorities. To an extent that it's not funny to pretend that there's much of a debate here.
Indeed. There have been a few studies that show that if you have a "minority" name, your odds of even getting past the first layer of HR bullspit is almost impossible, you don't even have to be a minority. Of course that's wrong. But then again, naming your kid something stupid just to name your kid something stupid is wrong too. I agree with DC Al too, the "right" kind of black person has no problem at all getting a job or getting promotions.
My votes went to minorities and introverts.
