Well, no. A lot of Jim Crow laws were in largely then-Democrat areas. Namely the southern, former Confederate states.
Where the meme is wrong is while the states have shifted in party preference, those same states and a few surrounding others are still perfectly willing to utilize state laws to discriminate against minorities.
Yet, I can’t think of a single state Democrat law in the last 10 years targets minorities.
Which, of course, where it falls apart.
What they’re actually furious about is segregation on a corporate level and affirmative action. Which absolutely should be addressed! But their way of going about it is to repeal policies and discontinue institutions that made it impossible for those states to continue passing Jim Crow-like laws.
Which is completely antithetical.
