That's an interesting idea. I've said something similar irl, that there's a bourgeois script.

There's no point arguing with someone who goes into it by default. Especially family members. Not everyone uses it, but for those who do, the only end point is an exchange of insults.

Good examples are reactionary TV 'news' presenters. They aren't interested in the argument or evidence, only providing their audience with another example to confirm their pre-existing worldview. There's always another quip, another reason why they don't have to consider a new idea. It's infuriating. But when you can recognise it, you'll save yourself a lot of intellectual hardship and emotional pain.
