...The vast majority of guys I know who have been in a lot of fights (me included) are quite happy never getting in a fight again? Like, there's definitely a few weirdos and dudes with anger issues who love fighting, but the shine wears off pretty damn quick for most people, and they'd rather avoid the fight in the first place? I really don't think real-life arenas and duels would work the way this guy thinks.

(I used to work as a bouncer in a bar, haven't been in a fight since then, I prefer keeping it that way. Also, fair notice, I wasn't actually a very good fighter- I was the average-sized, unintimidating bouncer, my job was to head off fights before they happened, so the bigger bouncers and bartenders didn't have to intervene, and I was good at talking drunks down. I wrestled a decent number of drunks when I had to, but that did not an impressive fighter make, I'd suck at Colosseum fights, lol.)
