I think this is a perfect illustration of the current cultural roiling over race. The original assumption, which Schlesinger goes back to in the second part, is that this woman is wrong for being resentful at having to constantly answer questions from someone who asks her what "black people" think about things. To Schlessinger, this is perfectly normal. After all black people are very exotic, unknowable creatures, and so it's completely understandable that people might turn every conversation into a discussion of how these strange others look at the world. The caller finds that uncomfortable and annoying,which makes Dr laura very angry at her. The question is, why?
Now it's possible that every conversation this woman has with the man has an appropriate racial context, but I doubt it. Most likely, and I expect that this woman feels, that her race is brought into it to draw attention to her race, to single her out, to make her feel her otherness in a white group, as the wife of a white man. After all, this kind of questioning isn't normal. Unless the subject at hand is explicitly racial, I don't think most of us bring it up in everyday conversation. I certainly don't ask my African American friends whether black people like grilled eggplant or what black people think about "True Blood." In fact, it's a subject that rarely comes up at all unless we are talking politics and specifically race and politics.
As the conversation continues, it's clear that Schlessinger is carrying quite a bit of anger about how "the blacks" continue to believe racism exists even though we have a black president. Evidently, that was supposed to have been the end of all that unpleasantness, particularly since blacks allegedly voted for him simply because of his race, thus proving their own racism. (The fact that they voted nearly unanimously for John Kerry, Al Gore and Bill Clinton as well would seem to indicate an ideological rather than a racial bias, but I've heard so many white people point this out that it's clear that quite a few see African American support for Obama as proof of black racism.)Dr Laura finds their lack of gratitude for being allowed to exercise their racism this way deeply offensive and is appalled that she is still having to answer for white prejudice --- even though nobody asked her to.
The immediate defensiveness, before the women even got out her complaint, is the main hallmark of this attitude. I saw Andrew Breitbart in person explode into an angry, spittle flecked tirade at the mild suggestion that racism is playing a part in current discourse. (He really went crazy, interrupting and screaming "racist, racist, racist" at the top of his lungs over and over again.) This obviously hits a very raw nerve with some people and they get extremely upset at the person who brings it up. I'm no psychologist like Dr Laura, but I would guess that zero to 60 reaction doesn't come out of nowhere.
After all, this woman wasn't calling Dr Laura a racist. Indeed, she was asking for her advice, thinking she would be sympathetic. But Dr Laura immediately gets agitated and brings herself into it, relating that she has a close black associate who doesn't mind when she makes jokes about white people not being athletic.(???) She clearly related to this caller's unnamed neighbor and chose to state her solidarity with him.
The rest of the conversation just got worse, as I noted, with both sides getting angry and Dr Laura ending up saying that the woman shouldn't have married outside her race. (Evidently one should expect to be treated as a visitor from a foreign planet if they do.)
This is a perfect example of modern racism of the "what do you have to do, kill Medgar Evers?" variety. No, this neighbor isn't being overtly racist, he's being passive aggressively racist, which is all the more annoying since it's impossible to confront, like all passive aggression. Indeed, it's laid on to the receiver --- "you're being hypersensitive." And it's clear that the perpetrator knows exactly what he or she is doing since when confronted they always behave with furious defensiveness. When it escalates, the real hostility comes right to the surface as it did with Schlessinger yesterday.
