What was he called? I do not know too many racial slurs that identify white people that are widely considered offensive.

What, did they call him stupid, terrible, "you are not from here," or any number of things and that is boiled down to racism? At least the person in the OP used the exact term that he was called. That word (that was used) is not simply a name being called that we all have been through as officials. That identified nothing else but his races. And if he was called names, get in line; it happens to all of us on the court in some capacity.
