What a depressing take. The whole reason we put 435 people in the same room (well, plus 100 people in another room) to run the lawmaking process was for them to convince each other with arguments. If we're going to make decisions based exclusively on who can yell generalized slurs the loudest, we're completely doomed.
Politicians don't convince each other via logical arguments, they convince each other with leverage, favors and all sorts of secret underhanded backroom deals. That's how power works.
I know it's a depressing take. It's a depressing world. And it's only getting worse. We're in an age where truth is essentially irrelevant if not actively detrimental to whatever cause any given person believes in.
