Apologies for downvoting you, I did so based on your original post of just "Seriously .. WTF?". I don't see his post as being WTF-worthy even though I disagree with it, nor do I condone any such posts since they add nothing of value to the discussion.
I interpreted his/her post as not against diversity, but against "diversification" programs like affirmative action as opposed to letting social entropy run its course. I agree with the sentiment somewhat but I don't think it meets the criteria for looking back and asking "what was society thinking?".
