The interesting thing is that the Dems used white supremacy and racism for a long time to try to keep part of the poor white vote. Then when that didn’t work any more, they switched to anti-white racism and race-based grievance mongering. The Dems have been a cancer on this country since they were formed.
In William Shetterley’s book “How to Make a Social Justice Warrior”, he brings up the point that social justice warriors focus on race as a proxy for poverty, but there are twice as many poor whites as blacks - in the 1960s AND today.
He then advocates for measures to abolish classism, but his condemnation of social justice warriors and “anti-racism” that let elite whites feel better about being elite and middle class blacks and hispanics who glum onto it to become superior to whites while doing nothing to help those in poverty is interesting.
