However, starting in 1954, the U.S. Supreme Court, the Supreme Court has steadily pushed back against these ideologies. These folks are losing elsewhere. Some Southern legislatures and the Southern Baptists have come out against the Confederate Battle Flag. Some southern cities have passed anti-discrimination regulations protecting LGBT's. The private sector is also joining in. However, it's far from over. In Texas, Greg Abbott, Ken Paxton, and much off he legislature keep fighting. In my classes, when someone took a obviously southern racist position, I merely stated that treating black people like second citizens was not going to make up for losing the civil war. That always ended the conversation.
Here's most of a great article by Richard Parker:
The political reality for the last 20 years is that social conservatism relied heavily, and particularly in the South, on new forms of discrimination: against women, gay people, ethnic minorities -- somebody, anybody. But now that discrimination is running against the current of history not just in federal courts but in the South itself. Urban Texas, for example, is not just diverse in every meaning of the word; it is fueled by diversity. Its cities have already moved to protect that diversity.
