Thanks for the honest, well-phrased question. To the first part, I think we are in way too deep in an ideological civil war and a large conservative segment believes their very way of life is threatened, and either sincerely or disingenuously they are willing to ignore all contradictory evidence and simply hang onto their gut feeling. There is also a pretty sophisticated industry out there giving these people alternative facts and talking points with just enough credence to feel they're having a legitimate debate with a legitimate ideological enemy.
Once you've gone "fake news" you can believe whatever you want, cite whoever you want. Also, and hear me out....some of their gut feelings are valid. There's a Venn diagram where we all have a lot more in common than we've been led to believe.
Now I'd like to say the facts are always on my side. But that's simply not true. Even if you go with the Archy Split: 84% Wrong/16% Right, you will have to face some pretty awkward wrongs. Liberals did plenty of trolling with claims and memes about Russia, COVID, Trump, the economy, etc., that didn't stand up to vetting or Snopes. Hunter Biden's laptop hardly absolves Trump, but it turns out it's really a thing. Nancy Pelosi's husband getting a DUI shouldn't move the needle in any political discussion, but I don't see any restraint when an obscure GOP clown gets caught doing something stupid in public. Sometimes when I see blatant rightwing horses#!t, I bring it here specifically because it should embarrass our handful of rightwing defenders, and I want to see them defend it. Trolling? Maybe.
I don't know about "nicer" but I think it's more honest and to the point to accuse someone of being willfully dishonest rather than trolling. What makes this a really good P&R Forum is that most posters ask for and supply reasonably good source material, and admit when they're conflicted. That may also be the reason why a lot of folks no longer post here. You kinda need to bring your A game. I didn't expect that from a football fansite, but hat's off to everyone who hangs in.
