Because some people grew up with primarily emotional rather than rational arguments, and the winner of an argument is opposite for the two cases. Later in life, they apply what they've learned to other situations, and fail to realize that they're only making things worse.
It's a negative feedback system, programmed into basic human psychology. Take that feeling of cringe. What if it bothered you more? What if it bothered you so much, you would do anything to avoid feeling it? Why, you'd lash out of course. And that searing rage gives you emotional validation, further reinforcing the reaction.
It's fair to say it's a negative feedback system, because emotional responses are always stronger than rational ones, even in well trained, rational people.
