To be clear, authoritarianism is rampant on both sides of the aisle. The gross resistance to even basic right wing ideology is proof of that (which to be clear I'm not calling Trump basic right wing). Hell the fact you're calling for violence is more proof.
Left and right, people want to force others to believe what they believe period. If you don't agree you get attacked.
We need to stop "fighting" each other, and start listening to each other. Then, instead of fighting amongst ourselves, we can unite against the common threat. Oligarchy, and plutocracy.
