One of the hallmark symptoms of alcoholism, before the alcoholic hits bottom, is denial. If one isn't puking on oneself, or is able to hold down a job, said alcoholic in denial will proclaim himself sober. Why? Because for the last forty years, being a drunk has stopped being acceptable or funny. Dean Martin, Red Skelton and many other comedians in the 1950's and early 60's made a career pretending to be lovable, laughable alcoholics.
Likewise, because racism has been so exposed as abhorrent in American society for the last forty years, it isn't acceptable to be an overt racist anymore, so many are in public denial, many even to themselves.
Enter the Tea Partiers and their supporters in what's left of the GOP. The Tea Party movement is virtually all white. The Republicans haven’t had a single African-American in the Senate or the House since 2003 and have had only three in total since 1935. No one in their right mind thinks that the virulent hatred that has been directed by the crazy right and the GOP at Barack Obama, basically a moderate liberal president at best, is because of health care! No one thinks that the violence threatened or actually acted out towards certain members of Congress is over policy conflicts. It is racism. Pure and simple.
And racism denied is still racism.
The preposterous proclamations of some lunatic racists that the fact that they like Clarence Thomas, Alan Keyes or Michael Steele proves that they're not racist is like an alcoholic saying he's not because he only drinks wine. Actions speak for themselves, regardless of the denials. This ever-shrinking part of our population will inevitably hit bottom. Hopefully, some will actually sober up before they fully self-destruct.
