I don't think so. I think it's a more modern phenomenon. Communism, Marxism, leftism, progressivism - whatever, in many forms. There is an appeal to the worst parts of human nature, and unfortunately, PT Barnum (or whoever said it) was right - "a sucker born every minute." Here we have many lined up with a lottery mentality, "owed reparations," something for nothing. And Johnson's "Great Society" enabled that to grow and fester.
I want to make clear however for anyone reading this but not reading my original reply.. I make a distinction between blacks who freed themselves before 1865 and those who did not. The former may be the ancestors of today's conservatives.
