Jurassic,

BITS pretty much has given answers that closely describe my line of thinking.

If I were ref'n a game involving a predominantly Mexican-American team and their coach yelled at me "you just don't like Mexicans!", he would get T'd up, but I wouldn't considered it a racist remark, I would consider it an attack against my integrity and impartiality. The same if I were called a bigot or sell-out. To me they are character attacks, not racial attacks.
