Re 1 and 2, both sides do it, but I find the whole "false equivalence" and "which side is worse" discussion nauseating and refuse to compare the two on the same scale. I think it suffices to say that neither can be neglected in understanding the current situation.
Stereotypically, right-wing propaganda seems to manipulate through brute force, and left-wing propaganda through selective negligence of cognitive biases. But even this perception is influenced by who does the fact-checking and how.
I can certainly understand your frustration, and I share it...but if we are really serious about climate change and various other issues, shouldn't we not only be willing, but strongly desire to determine with certainty whether the methods we use to govern our behavior (which were designed in relatively archaic times) are adequate to face the challenges of the 21st century?
If this was any other kind of project, the quality of leaders and design of systems of leadership would absolutely be brought into question by most people - does it not seem more than a little weird that the political realm [1] is treated as if it is radioactive, beyond even simple discussion?
Does this seem rational?
[1] Well, ours that is - we seem to be more than happy to overthrow ones we do not like, and even consider it righteous.
