It's the only time when rephrasing what someone said isn't a critical listening skill and incredibly persuasive. If you're already digging your feet into the dirt, doubling down on your own morality, every discussion feels like an attack.

"What if the homeless man is responding to systemic pressures that aren't obvious to you?"

"What if other ways of organizing society could be beneficial?"

"Have you ever considered why you value the rules so much?"

Any of these could shine a light into often unobserved assumptions. But if you entrench yourself you lose out on the chance to learn. You could very well look at it and decide that you are a stinky stinky lib, but even then you'd stop being a slave to fate because you're at least making the conscious choice to be a class traitor and a moron.
