This video was cringey, but illuminating.
When the guy from CNN calmly and reasonably informs the man with the beard why his beliefs are wrong, "nah" is the response. Facebook posts full of misinformation and conspiracies drove them there - and it looks like a pretty large crowd - and fact checking doesn't work. They'll easily believe an election official posted a video where they're burning votes for Trump, but when it's explained why mail-in ballots went overwhelmingly for Biden suddenly they're skeptical. That one woman seemed reasonably intelligent, had some understanding of social media algorithms, but still failed to grasp how it influenced her.
Trumpism might be ill but these people are not going anywhere. All we can hope is they're converted to a new "cause" and that cause is not too awful. But they'll need it. They're still ripe for the picking.
