Your comparison to trophy hunting makes no sense. One entity killing another unwilling entity for sport is no comparison to two willing participants engaging in a physical contest with rules and a referee where at least one of th goals is to minimize long term damage. Agree on football and boxing, not a fan of either. As for MMA the jury is still out but I hardly think equating it with slavery makes sense because you "can't imagine" it's safe, even though you don't have the data. I mean, comparing that to literally owning another human? All sports have physical risk, even solo sports. Does that mean that when I go rock climbing, I might as well be owning slaves or torturing animals?
