White people are cool too: I don't know any rappers. I don't watch reality television. But I do know that Uncle Luke's article claiming Karl Rove is racist for his ad criticizing President Obama for being too "cool" ("Luke's Gospel: The Real Message of Rove's Attack Ad: Obama Is Too Black to Be President," Luther Campbell, May 10) is itself subliminally racist. It implies only blacks can be "cool" and therefore is a racist argument. I believe the real question is whether Obama's actions have been presidential. That is a question that should be decided by the voters.
