I don't actually agree with (what I know of the) PayPal hiring decision in this case, but the part I was replying to, and should have quoted initially, is: You're actively discouraging diversity of culture (which is not directly the same thing as diversity of gender/race, but it makes it a lot harder to have the latter). My point is just that it's not at all clear that encouraging uniformity of culture is automatically a terrible, productivity-destroying bias, and that I have worked at places which strongly preferred that candidates "fit into" the organization's culture while at the same time being strongly committed to diversity in gender, race/ethnicity, and so on. These are definitely separable.
