Well, the folly of bmulligan and elprincipe is that they seem to want "equality," but don't seem to want to do anything about the status quo, thinking it will work itself out.
Here's what they don't get: affirmative action will NEVER go away. Before we had affirmative action policies, we had affirmative action policies. It was "whites only." To act like that hasn't gone away is something that's not really worth debating, as it's an institutional equivalent of saying "there's no more racism in society at all."
So we have two forms of affirmative action: (1) those systems that, formally or informally, provide advantages for some minorities; (2) those informal systems embedded into institutions that keep minorities out in the first place.
Look, we don't have signs that say "whites only" anymore, but if you think that there's no racial penalty in gaining entry if you're nonwhite, you're a fool and a liar. "Whites only" is still the case, it's the default elprincipe and bmulligan want to deny the existence of until confronted with the fact that racism still exists, and then pooh-pooh it away, saying "we'll never get rid of ALL racism."
But the fact is, that "backdoor affirmative action" is more powerful than any formal policy that helps out nonwhites. That's what they're scared to admit. They're the kind of people who howl at Devah Pager's research, and can offer up nothing contrary other than blustering, denial, and post-hoc cognitive dissonance repairs.
But the funny thing about their argument is this: they'll admit that "racism" is something that, since it's a mindset, isn't something we'll be able to eliminate in its entirety. Knowing full well that we can't get rid of it, then, the obvious solution is to let the default informal affirmative action policies remain in place, and deny those equal opportunities (equal opportunity for preferential treatment!) to nonwhites.
It's more white people having no idea what this world is like, and thinking that nonwhites just have to will themselves into positions of power. Heh.
