If it's one item in a long list it seems reasonable to take it as one factor, especially if they're, in the case I've encountered most often, twentysomething male nonimmigrant whites who grew up in an urban area in the northeast or west coast, in a middle-class or better family. Any one of those factors aren't particularly predictive, but taken as a whole they narrow down a culture with some accuracy.
No, the problem is that in a list of eleven points, you pick one to make a fuss about - alledging that the original poster said them being white was a bad thing.
It was in a list including "two degrees" (good) and "burned out twice in 6 months" (bad). Why do you take away that he said white is bad?
Why do you have an issue with skin colour being mentioned, but not age or gender or which college the degrees were from or how many hours they work or which specific tech they use? Why are you pushing so hard to make a great big racial controversy out it?
