Politics is the mind-killer. Even those of us who wish to be rational and practice rationalism, suck at applying the methods of rationality to politics by default.

I don’t have a magic-wand solution to this (and I’d be surprised if such a solution exists), but we’ve just witnessed what happens if you let people argue endlessly in bad faith without consequence, and what happened was not good.

Perhaps your way is the least-bad outcome overall? I wouldn’t know, but you do not appear to have made that argument.
