It's pure lunacy.
Lunacy and identity politics. (Not that those terms are mutually exclusive.) The people pushing for it are trying to drive a wedge between voters to capitalize on their emotions.
Exactly. This is why I don't what a person's feelings are when it comes to politics any more. In fact, I'm very happy to poke them and keep poking them until they can't see straight because pure talk will never get someone who is rooted in their emotions to change their political stance. All you can do is make them so crazy that they can't think straight (so that it's even easier to discredit them), they can't find someone to have kids with and if they do then the kids will be even crazier. Within a single generation, those people (let's be honest here, mostly democrats) will lose all credibility and political strength.
When that generation dies out or goes completely insane, we can go back to not having polarization in politics and get things done collectively again.
This is (a fringe) part of "accelerationism" by the way.
No one alive today was a slave. No one alive today owned slaves. Period. Why do we have to have a conversation about this? It's pure lunacy.
