Is it an affectation that they’re trained to deploy? (If so, why?) Or is it just a natural thing that happens in the very specific circumstance of being a politician on the campaign trail, and that’s why no one else seems to do it?
I don’t think I’ve seen it in any other context 🤔
Cheers!
Remember Biden’s “I did that!” (lying) stickers that were placed on gas pumps by maga freaks? It’s trivial to put your political opponent in an ad where they are saying something they’re not, because pointing is seen as an aggressive gesture by the people coaching them for speeches, debates, etc. So they do the silly thumb-point for emphasis recommended by political strategists…
