She's pointed out that politically the issue of race being used as a wedge issue is to make white's fear blacks and what they would do if they aren't kept suppressed. This is the same with Hispanics but without the dark history of societal violence that's the case with the white/black historical relationship of slavery and all its accompanying fallout. After the Civil War black men had to be persecuted and lynched because all they ever thought about was raping white women. Now with a black man in the Whitehouse their worst fears are getting closer to manifesting. Obama is going to come and get them in a fit of vengeful murder.
Sarah Palin's 'death panels' talk was a thinly veiled reference to this idea and was heard loud and clear by the teabaggers (sorry, they haven't risen to the level of legitimacy for me) who through the McCain/Palin candidacy have felt they were given permission to voice their racist swill. The woman who told McCain that she was afraid of Obama because he was a Muslim was the person who voiced that fear, not hatred, of what the teabaggers believe deep down. The fact that they insist he's a Muslim is also telling. Fear of another attack by Muslims is prevalent now. They are the enemy right now. They've taken the place of the Evil Empire, the Soviet Union. They've seamlessly substituted Obama for the Evil Empire, who were also out to get the US and it was only through military might and aggression and superiority given to the US by God that Reagan 'defeated' them.
So what sounds like total idiocy to our ears is heard loud and clear by those who fear black people. Obama is here to take everything away from them and give it to black people and reverse the roles so white people will be oppressed and relegated to grinding poverty and servitude. Deep down they believe that the races are divided into those who are righteous and favored by God and those who are inferior and that they are Good and all other races are Evil because that's how God created the races. So naturally they feel this is a fight to the death between good and evil. Evil being, of course, the other races. And if Evil wins, then Good will be punished because they simply can't grasp that the world could be a place of equality among the races. It isn't within their ability to understand that concept. The only way life can be is the division of Good and Evil and the never ending struggle of who has the most power. It's survival on a deep sub-conscious level.
