Last time I heard it was northern whites vs southern whites in the 1860's. The Washington Democrats keep the coalition in line with the bribe of Affirmative Action and by restricting immigration almost exclusively to non-whites. As a matter of fact, of the few whites admitted to the country, most are Jewish, who also can be counted on to vote Democratic. I wonder if immigration may also be driven by individual personal need around the world. Let's see, women and children are still enslaved and abused.
People of color see their nations ruined by capitalism and imperialism.
You don't hear of too many white countries going down the tubes. It may be that more women than men, more people of color may believe that the US will give them the best shot at a good life. To ignore these things and retreat into fatuous platitudes strikes me as bad thinking. There's no liberal plot either.
