The fact is the southern Dems were called Dixie crats. They were titular Dems, but voted for many Repub programs and fought any programs that helped minorities. When LBJ passed the Civil Rights Bill, the southern Dems moved en masse to the Repub party, their natural home. They have been there ever since. LBJ said we lost the southern vote for a generation. It was much, much longer. The Repubs are the racist party and have been your whole life, They are also anti-gay. Do you understand how backwards your opening line was? You should rethink it and edit.
You show you know nothing about your party. All Dixiecrats except for Thurmond stayed democrats
