Or, alternatively, it will be largely about education level as well.
I tend to think that the strongest explanatory factor is class rather than race, although race and education probably correlated strongly with class and vice versa. It's a pretty tangled set of causal factors. But, you're right in that race is will certainly continue to be a large part of it.
Interestingly, those who are most apt to declare their white pride are, it seems, drawn disproportionately from the lower, less educated classes. My hypothesis is that their fixation about race and white pride has a lot to do with their desire to elevate themselves above the [N-word], in recognition of their own lowly status, so that they can be comforted by the thought that they are at least better than someone else.
I don't disagree with any of that.
