There is only one right way to live... theirs. Anything else is wrong and must be rooted out. They believe people can only be happy when living life their way. They can never be happy until YOU live life their way. They take other perspectives as an insult. They are offended by things that have nothing to do with them because everything must be about them.
I have often said that trying to get the Left on the same page is like herding cats. That's a good thing. I am a moderate, centrist, liberal and I argue with those within my political sphere. I disagree with members of my own "team" on various things. But at the end of the day, the Left end of the political spectrum allows a tent for those arguments.
On the contrary, the Right, over the past 10 years, has sidelined and primaried every voice that does not fall into lockstep. Liz Cheney, the conservatives conservative, has no place in their vision for America. Republicans like Bill Kristol no longer have a political home. Mitt Romney, who ran for president under their banner, is sidelined and despised (in Utah he was booed at our convention).
So, when Vance declares that he was just being sarcastic, he is lying. He does not believe in freedom... other than the freedom to think his thoughts and live life his way.
