Don't subscribe to the notion that you should be fighting for life if it's in jeopardy.
No?
Your advice is roll over and die? Should I lift my skirt for him, too?
The idea isn't to totally maim your attacker so he never does it again, it's to stop him to make him realize how much more you can/could do.
That's what Karate taught me. and what you're describing to me sounds like the philosophy of the baddies in The Karate Kid. You know, "Strike hard, Strike first, no mercy!"
The Karate Kid? Seriously? This is worse than quoting Oprah.
If ever I'm attacked the very last thing I'll be doing is assuming the crane position. Sorry, Chuck, what you're talking about are ego fights where impressing or intimidating your opponent is about all you need to do.
In cases where your attacker is hopped up on drugs or adrenaline you don't want to dazzle them you want to disable them. You also don't want a prolonged fight with someone who is stronger or has more endurance than you. If your attacker has a knife or a gun you're not safe until it's out of their hands or you are well out of range. These situations don't tend to end with, "cool move, man".
Broken bones heal and joints can be realigned, not that my concern in a situation like this is going to be for my attackers well being. Cripes, if he never does it again...That's a good thing isn't it?
Another reason systems like Krav Maga and others are a good idea. Formal martial arts like Karate and others take
years to learn to a point where you'd be effective in a fight. Courses designed purely for self defence will teach you only the effective moves for getting out of an attack.
