I had an argument with someone earlier who commented on a post I'd made and was all in on the MAGA position. They accused me of ignorance and I invited them to post some video of supposedly 'war-ravaged' Portland (a phrase used by the WH press secretary recently). First they told me to go and look on the timelines of their favorite right wing influencers, and when I declined to go on a wild goose chase they followed up with a mix of invective and random factoids, like the Portland fire department responding to 9 fires in the last 24 hours. (Since I live near a fire station in a similarly sized city the idea of a few minor fires every day impresses me not at all.)

It's tedious and unrewarding, but calling people's bluff is somewhat effective.
