I try not to get my heels too dug in with online arguments, lately. I am kind of embracing the attitude of “ok, you won” and not spend a whole lot of time or energy on it. If I feel myself going in that direction, I remind myself that this person is not going to change my mind and I’m not going to change theirs, so back away. People may take it to mean that they “won” but I don’t care. It doesn’t matter what they think.
In real life, I see some crazy things with politics, like with the ladies in Congress insulting each others’ physical traits the other day (Marjorie Taylor Greene vs. Crockett) but that seems to be more the norm. The NY Times had an article about how it’s more commonplace now since Trump was calling women “fat” and “horseface” so schoolyard namecalling is no longer shocking. It’s not even schoolyard any more, since kids at school are taught to try to be kind to one another.
