One problem I've noticed with all of this is that there always ends up being a kind of sacrificial white group either in terms of employment or in terms of their cultural heritage being catered to by the state at a local level. Resentment towards this breeds the birth of white supremacist groups and so on. It's happened repeatedly in history. The thing is, to a specific sub section of white people, middle class liberals who perhaps base their judgment on this from a reading of whiteness studies literature and so on, well they might think that's probably a process that we will go through on a route towards equality. My view is that such people, not to fall into an ad hominem tirade, but such people might do well to re-read their own books. Basically, from the point of view thay you have been given by your culturally insular media, you may see your nation's manifest destiny as bringing an end to identity conflicts globally and so on and so forth, with the associated ideas of the noble savage Other none white people from The Searchers and Dances with Wolves. Well, to be blunt, it's more complicated than that. The way people think about identify is seldom absolutely rational from what I've seen. Humans don't naturally react to inequality in the way we may presume, people are often very susceptible to believe and almost be consumed, in a way, by the mythologies of the day and the manner in which they justify unequal human relations, be that racism, tribalism, religion, ideology or whatever.
As far as I can see, this ends when humans stop being susceptible to it, which is never. These things change around and after a while, behaviour according to an old mode of the mythology is an indicator of a lower class person where it might have been the opposite some time ago. However, the unequal human relations continue. The once pagan king gets a bit of the crucifix fastened to his crown.
This isn't an argument against progressive politics though.
