Middle-of-the-road person: "You are not in a culture war or an ideology war. You are both in a CLASS war, run by billionaires who are the REAL source of your pain. They use the six corporations that control all the news to distract you and keep you fighting with each other so that they . . . the rich . . . can run off with all the f*cking money."
I think that the key difference here that would make two people who agree with this statement a centerist or a leftist is whether or not they feel visceral hatred for the right or if they treat them like human beings.
