Like I said above you. Call him a cunt all you like, I'll agree with you. But folks need to leave the racist shit out until he's actually proven guilty.
Racially abusing someone in a heated moment doesn't make one a racist. Most people have this potential in them if nothing else they're at least keenly aware of the gravity of such words and may still reach for them if frustration mounts. When you know where the lowest of the low is, there will always be a temptation to stoop there when you're super aggravated or frustrated.
I've seen more seemingly inoccuous racist attitudes in Asia that are par for the course here and actually qualify as "XXX race is superior over YYY race." To me this is worse than a random moment of diarrhea mouth.
