My family collected reference books but they would still do this. I would spend entire holidays sitting there and listening to them debate whether Mack the Knife was still #1 on the charts on January 1st, 1960. I never heard anyone listen to Bobby Darin ever, but his career was discussed ad nauseam.
Just look it up or move on! It's the conversation equivalent of a rain delay.
I guess it works if everyone is equally into a subject but that's pretty rare and by this point I've been put out by it so many times even if I am interested, I'm not interested.
Then why do you want to argue about it?
I just don't want conversations to grind to a halt to figure out a piece of trivia, moving on is fine as is looking it up.
I'm the sort of person to argue about which sportsperson was better than which other. The stats are just the stats.
Admittedly I'm a bit older, but with my friends I explicitly say lets argue it out. That's part of the fun of debating when something came out or who was in what movie. But, I didn't have a cell phone growing up so wondering about something and trying to reason it out was normal.
