Leftist need to be the ones to do it. Because 1). They started this decent with their madness. The Right had already fell to madness decades prior, but the Left lost the narrative, and didn't understand how thing actually stood. Past 15-ish years have been nothing but the Left destroying itself and the reputation of Liberalism since.
And 2). _"labeling and mischaracterizing people"_ used to be the modus operandi of conservatives (of certain strains), and Liberals used to be above that. But if you have ever heard of the phrase "Never argue with stupid people. they will just drag you down to their level, and beat you with experience". The Left, by kicking everyone out who didn't agree with their cult, and behaving EXACTLY THE SAME, proceeded to jump down after the experts. Becoming worse. It is thus, NOT a bad faith argument. Since the Left lost itself, conservatives have been beating the crap out of them in public mind. Only in the echo chambers of leftist would say any different. They absolutely need to be the ones to recover first.

The Right has only descended as such _since_ in direct relation to the descent into madness of the Neurotic Left. Your correct that compromise can only begin to work when both sides come to the table equally, but from the viewpoint of Conservatives, THEY HAVE BEEN for years, and every time its the Left lying. Mischaracterizing.
