Surprised this hadn't been brought up on here, having had a quick look around, since this story's been spoken about nationally.
From the bits I've seen, there seems to be the media narrative, that as a culture we have morally transcended the allure of racial supremacy as a possible basis for identity, and that when things like this happen, its time for us to collectively shake our heads at our mistaken faith in that unanimous transcendence. The problem with this is that by default it leaves two insufficient solutions: either to deny it as an anomalous fringe occurrence, or to take up a position of 'bad faith'. The former is insufficient because its simply not the case, and the latter, too, as it would inevitably circle back to that bad faith being rooted in gender, race or class. Take the image above this post as an example - why does the journalist not circle the other men beside the one that is.
Beyond the typical position that "they are evil incarnate" there is little nuance around these issues. People fear being thought to justify racism, and therefore, be so themselves.
As an example: to what degree are the racial tensions a proxy for cultural ones. How much of it can be put down to male status competition. How abnormal is a (primarily) racial basis in identity. How effective is shame, or the threat of it, at achieving the widespread, or even individual, transcendence of racial identification. etc
There are things this culture has to come to terms with before any real progress can be made. If that doesn't happen things will get worse, and it will become increasingly obvious that these instances are not the exception, but the rule.
