I assume that your attitude would be the same if it were a group of white neo-Nazi skinheads yelling racist epithets at a nonwhite sports player in a packed arena during a major sporting event?
1. It sounds like one fan.
2.If white people don't understand that black people generally hate their guts, they are delusional. To expect government or some kind of authority to back up a white male in an abusive or hate crime situation they are stupid.
Because I know these things to be true, does that mean I have to hate them back? No. It does mean I need to take each man as a man but also understand that going down to South Oak Cliff may get me killed because I am white. A black man going into Highland Park will not.
