I do from time to time. I don’t bring it up though. I have other friends that I spar with to keep me thinking coherently. It’s a long car ride. 35 min one way.
He lives on assumptions and random “studies”. I’ll say something and he’ll refute it with a random study that is done by elementary kids (not really, but he pulls them out of crazy places).
My all-time favorite comment of his was that He wouldn’t shoot to kill someone that was raping his mom or sister. You can’t argue with that. It’s illogical and stupid. No point in lowering myself to that line of thinking.
Come back the next day and tell him you looked up the study and it either didn't exist, or didn't say what he said, and he'll be forced to not cite these fabrications.
