I find it hard to believe that the average wingnut is genuinely happy with their healthcare options. So where is all their teabaggin’ rage coming from? The simplest explanation for their "rage" over healthcare is that it is just a proxy for their racist hatred of President Obama, our first black president.
I think that the bulk of wingnut rage that is directed towards Obama is because he is a black man, and has little to nothing to do with his policy proposals. "How can it be that we have a n----- president?!", they think. "This is America!" In their narrow wingnut universe, this is an impossibility. Consequently, they want to see any and all of Obama’s policies fail so that their sense of order – white political, economic and social dominance – can be restored.
I think that the Republican/Wingnut party should be called out on this. I think that the person to do it is Joe Biden. He has the candor to be frank about the role of race in the current politics. Obama would be mercilessly criticized for "playing the race card" if he even mentioned race as a factor motivating Republican hostility to his policies. But Biden would be able fight that fight.
