but if you're going to differentiate based on what they are allowed to do, then none of them, not even mma, are fighting.
you can't stomp people's heads in MMA, you can't headbutt or knee the head of a downed opponent.
..IF we are defining a fight as something with no rules then only vale tudo is actually fighting.
"The hero and the coward both feel the same thing, but the hero projects his fear onto his opponent while the coward runs. 'Fear'. It's the same thing, but it's what you do with it that matters". - Cus D'Amato
