You asked a question --- orthogonal to my questions, which you really still haven't answered --- and then feigned offense when I answered it. If you didn't want to talk about "emotions", well, neither did I. Why'd you bring them up?
Here is another way to read the questions I asked: "perhaps the answers to these questions explain why a normal reader might snag on the way you worded your previous comment and have to ask themselves whether they were taking race-troll bait". Not: "Chris should make different points", but rather, "here are some tools Chris might think about using to avoid giving the impression that he's race-trolling."
So again, I'd ask:
* Why go through extra effort to find a data point less favorable to black people than the one the document already presents?
* If the point is that there are public policy debates to be had about fairness versus demographic blinding, why pick on black people in the first place? A comparison between Asians and whites makes the same point, without requiring you to ever write the words "deadbeat blacks".
