This morning Rush Limbaugh related a story about Eagles' quarterback, Donovan McNabb, not knowing that an NFL game can end in a tie. Some sportscaster called him a "cement-head" and another sportscaster, defending McNabb, said that calling McNabb a "cement-head" must have stood for something else. I am assuming that person thought it was a racial invective. Are you KIDDING me?
I am reminded of Joe Biden's comment about Obama early in the nomination process. About Obama, Biden noted that he was articulate. Black leaders took it to mean - "He's articulate - for a black guy."
Now it's just fine to say some white person is a cement-head when appropriate. Like Tony Romo is a cement-head for dating Jessica Simpson who IS a cement-head.
