Yeah, that's not what I said or an answer to the question I asked, but at least it's a start.Republicans have not changed from anti-racists into racists even though Democrats love to make that false claim.
What I've noted, and what is observably and demonstrably true, is that the South, a hotbed of racist resistance to racial equality before the law, began to move from being a bastion of support for the Democratic Party to being the go-to foundation for the Republican Party over Johnson's use of the larger party to push forward with desegregation and the Voting Rights Act.
As this happened the Democratic Party became the party of minority interests, holding onto the dying arm of unions, who were losing their strength in part because of that defection and its reflection in their rank and file.
So today the general rule would be that racists find a more comfortable home in the Republican Party...at least the white variety from the still dominant culture.
You lose your intellectual thread and credibility with the last and a want of context. The first part is absolutely true. That last sentence is not.History shows that the Democrats are responsible for most (if not all) of the racist legislation in the last 160 years and Republicans were responsible for most of the anti-racist legislation in the same period.
Democrats are the racists
