The problem with situations like this is that it's something a white person doesn't even have to deal with. Most if they haven't had it happen to them can't even comprehend what it's like.
I lived in a part of the US where my demographic was only 4% of the population for 150 miles in any direction. I assure you, racism, slurs, and race-based violence against my minority group was rampant.
But the total shits given was zero because I'm white the population was hispanic (about 50% mexican nationals).
The assailant has no right to hit anyone for something said to him, but I get why he was pissed off so I don't think it's likely something endemic to the character of the assailant. Depending on the damage done, some length of parol w/ no time served is probably called for.
