I don’t understand this attitude. If an argument is good, why wouldn’t it be valuable or matter? I think it would benefit people a lot if everyone put more thought and consideration into their arguments, especially in the direction of conveying some original thought that isn’t just a remix of the same tired propaganda style rhetoric everyone’s heard a million times before. “Winning” doesn’t matter, but collaboratively thinking about things with other people matters, and a good way to do that is through argument.
