PJ, it's hopeless. You have to realize: you, I, and the other sane posters here have an objective standard for what is and isn't factual. Our resident conservitards have a much different standard: "Do I want to believe this?" So, when Tommie-poo sees something critical of Biden, or Boiler sees something that fosters white supremacy, or when Stalker sees, well, anything he thinks he can use to start an argument, they automatically and reflexively believe it. In fact, they lap it up like starving dogs.
So, as I'm sure you've realized, providing them with sources and facts doesn't penetrate their brains at all--because they don't want to hear it. That's why they constantly scream at us and call us LIARS LIARS LIARS. (It's a tactic David Miller learned during his four years in third grade.)
I know you're used and inclined to engaging in civil discussion, but these people aren't the least bit interested in that. That's why they start shouting at you and call you a liar whenever you school them. That's why they weasel away whenever you refute them.
I for one don't want to talk with any of them about anything, any more than I would want to dance with someone with bad breath, body odor, and fleas.
