A Brief Note on Dixiecrats
It's common for conservatives to point out that the Republicans were the party that abolished slavery and that the Democrats defended it. The standard response from Democrats is to claim the parties have switched places.
Maybe the conservatives should criticize “the identity-politics party” or “the party opposed to the 1%” or “the party that shouts down dissent” or the “party that regards disagreement as offensive” or …
In the other direction, I doubt if the Republicans have changed much.
