Basically, Biden bantered with an ordinary citizen and critic who supports the other side, everyone laughed, and nothing bad happened. The fact that this very normal and welcome democratic moment is presented by some as a gaffe tells you a lot about the people doing it.

The clip of Biden trading hats with the MAGA voter is fun; dude makes jokes about the president, he goes along with it. ("There's always one in the neighborhood!") Yet so many weirdo REACT videos portraying it as a crazy gaffe or Trump endorsement https://www.youtube.com/watch?v=afTPBx4cmY8
