Funnily enough there is an Ian Atherby concept that separates consensual with non consensual violence.
I don't get that there is a difference except that obviously if you don't give the guy any warning you will get extra shots in.
I think there’s two differences they’ve got in mind:
1. In a non-consensual fight, you typically don’t realize you’re in a fight until it’s already started. True enough, and it changes things a bit. You usually have to play “catch up.”
2. They think there’s far more dancing around when it’s consensual, like a pro boxing match. True enough until once you actually engage; then it’s like everything else.
Other than the element of surprise and maybe the first few seconds of looking for your in, I don’t see much difference between “do you want to take this outside?” and the guy who didn’t say anything and started throwing fists because you looked at his girlfriend the wrong way. Once that initial contact is made, a fight is a fight. The rest is just semantics. No need to base an entire system out of the differences. Saying “my system is designed to defend in a non-consensual fight” is just an excuse for getting your a$$ kicked IMO.
If you don’t see the punch coming, chances are it’ll hit you and end your night, sucker punch or not.
I’ve been in quite a few “do you want to go outside?” and fights that started before I knew I was in a fight. There really wasn’t much difference. It’s not like consensual was always a boxing match and non-consensual was always a wrestling match. A fight is a fight, regardless of how long you’ve got to measure up the other guy right beforehand.
It’s not like every consensual fight is Duran vs Leonard 2 (the whole thing, not just the no mas part) and every non-consensual fight is Hagler vs Hearns.
