One could plausibly make the case that the best way to understand the real political divide in the US is between those who want our political discourse to be policed, limited and controlled by the Kate Starbirds of the world, and those who don't.
Correct. I talk to many people of many different political persuasions. None of us want to silence the other, even when we disagree. That's a healthy society. Authoritarians have no interest in a healthy society.
