Do Obama/Osama slips of the tongue reveal racist attitudes?

Over the last few days, in the flurry of excited talk about the killing of Osama bin Laden, I’ve heard at least five slips of the tongue in which the name “Osama” was substituted for “Obama.” Do these "Freudian" slips of the tongue reveal racist attitudes equating the U.S. President with dangerous terrorists?
