People can think whatever they, that doesn’t make it real. Your argument is a false equivalence. Even if both sides do it, it’s not of the same proportion and that matters.
Objectively, Republicans are not compromising, they are often explicit that they are waging a scorched earth zero compromise negotiating style. The heritage foundation wrote the template for the ACA in the 70s as an alternative to Medicare expansion. It was then Bob Dole’s plan when he ran against Bill Clinton, and was Dole’s alternative to Clinton’s health plan. Then Romney passed it in Massachusetts. But when Obama consciously tries to compromise and meet in the middle instead of participating they say it’s communism. They spent a decade to repeal a plan they invented.
Similar with global warming. Cap and trade was a republican idea. Where have they compromised? Instead they are demonizing all of science to shift the conversation to absurdity.
How about the 2008 stimulus. Obama has to fight tooth an nail for 800 billion even though economists say the output gap is $1.5 Trillion and the stimulus needs to be bigger. But Obama agrees thinking when it’s clear more is needed more will be available. He underestimated how much Mitch meant it when he said “the single objective is to make Obama a one term president” and was willing to let the economy struggle if needed. Then Trump gets $3 trillion with Democrats compromising all over the place.
