It just suits your emotional needs to label him as a racist, TIA. It's a standard reaction. The mere fact that Obama IS half-black means that anyone who criticizes him will be labelled a "racist" by a large number of people, regardless of whether or not they really are. It's kind of like being labelled "anti-semitic" by a certain crowd if you criticize Israeli policy....inevitable!

Being accused of being a witch in Salem...worked exactly the same way, and if so accused there was no way on Earth of proving one's innocence. The mere accusation itself serves as judge, jury, and executioner....and it makes the accuser feel like he's "saving the world" for the righteous too! Very satisfying.
