The Logical Rudeness (and a little bit of Plain Rudeness — generally a somewhat angry and mocking tone) were strong in someone I was recently debating about the desirability of indefinitely long lifespans.

They make an argument. I offer a counterargument. This may go back and forth a few times, but in the end, they would usually then switch to another argument without acknowledging my last counterargument at all. And then, later, they'd often switch back to the same point they made before and refused to acknowledge my counterargument to it, as though I had never said it. Very frustrating.

(This is why I'm not interested in going into politics anymore. This is the structure of pretty much every political debate, and I have a very low tolerance for it.)

I think I'm going to start asking people to accept this precondition if they want to argue with me: When one of us makes a point, the other must offer a counterargument or explicitly concede the point. We're not allowed to move to another point without doing that first. Concede or refute, don't ignore. And if one of us later reuses an argument we previously conceded, the other person gets to dismiss it without repeating their refutation.
