Mrs.LL laid down the law months ago that there would be no discussion of politics at Thanksgiving. And Mrs.LL's edicts are generally followed by anyone who doesn't want to lose a testicle.
There were two minor exceptions:
A brief discussion over the kitchen island between her mildly-racist-but-solidly-anti-Trump father, her similarly situated brother, and her MAGA/Qanon-adjacent cousin about race. There's kind of the usual arguments against CRT and the denial of systemic racism in America. And then I bring up redlining. Blank stares all the way around. So I quickly give a lesson on what redlining was and its ongoing effects. And after 20 years around these people, they know I'm not bullshitting or making stuff up, so there's just a general "Huh--I didn't know that."
I don't know that it changed any opinions. But it ended the conversation. And perhaps it planted the seeds of further thought.
The other one was with my nephew. He's young and idealistic. He says he's voting for RFK Jr. Oh, and he's in a swing-ish state (Virginia). I absolutely went off on him. I told him he might as well vote for Trump, and that would mean among other things that his super-hot girlfriend that he brought to Thanksgiving wouldn't be able to get an abortion if one slipped past the goalie. And he'd get to explain to her why she had to carry an unwanted pregnancy to term because of his disdain for the two-party system.
I think that one may have had more impact.
