Entering an argument in good faith with someone who obviously is arguing in bad faith is pointless. The biggest problem is often that those who make bad faith arguments don't know they are doing so. Instead they lean into semantics to justify making bad faith arguments. Then start doing the "no u" thing before they start whining.

I choose to yell first because it triggers these types of defensive responses they would do anyways at the end of a good faith discussion. Kind of like splashing the antichrist with holy water so we can just know who they are.
