No, in this case the explanation we all naturally jump to is that the guy doesn't care much for black people, based on preconceptions about him.
I think we can all agree that he's a guilty-as-sin fucktard, but to be saying that his feeling of 'threat' was based entirely on skin colour rather than, say, the style of loud music being played is actually kind of a tricky position to take. There's got to be a concern that we're saying he must have been biased against young black men based on the fact that he's a middle-aged white man. Would he have been more 'threatened' by a black man in a suit working on an iPad or a white man playing rap music loudly?
Race is probably a factor, but right away we've got a whole load of people jumping in to act like it's the only factor, and while I wouldn't go as far as BPRD, that is kind of icky. For a whole host of reasons.
