As martial artists we strive to head off conflict before it ever gets to technique.
Except for the times when we believe it's inevitable and start it on our terms before they are completely ready so as to end it quickly.
We use verbage designed to de-escalate a situation. One of the things I can't really ever remember concentrating on during my training are the specifics of how, exactly, to do that.
That's because very few people are trained in it. Most martial arts classes are about how to prevail in conflict of one sort or another. Even though Aikido encourages a humble and peaceful attitude the expression is physical, not verbal. There are graduate programs in mediation and conflict resolution. There are courses like
Verbal Judo which specifically address these issues. There are some teachers who have personal expertise in the area and try to integrate it into class.
It's also a very culture-specific thing. Japanese are not Javanese. Americans are not Andorrans. The same signals can have very different results. One of the things that sunk the *spit* Rajneeshees here in Oregon was their use of Indian conventions in an American political setting. As one of their former officers said "When you raise a sword to an Indian he submits. We though Americans would act the same way."
We hear, "You have to do everything you can to avoid a physical confrontation"..."Fighting is a last resort"..."If you have to use technique then you've failed somewhere along the way"
One problem is that all of these are at least partly false.
There are things that are much worse than getting into a fight. I will take a reasonable amount of crap to keep the peace. I will not allow friends or family to be put in danger or even humiliated.
Sometimes a little violence now is the best way to avoid a lot of violence later. People who want to take something from you will generally do so until they decide that the price they are about to pay is greater than whatever it is they're about to take from you. The earlier you raise the cost, the less you have to do down the road. And once you get in the habit of giving in or backing down, even if it's only for a couple minutes, you have made it more difficult to move towards the proactive and to get him to stop whatever it was he was doing to you.
Unless you have incredible powers of persuasion and the Divine Aura of Compassionate Kwan Yin you can't control another person's actions and desire. You can try to de-escalate. You can avoid provoking him. But in the end his actions are his responsibility, not yours.
The first serious fight I ever got in was over something I had absolutely no control over and which he was dead set on using to start a fight with due to training he received from the cradle. Did I want to hurt him? No. Of course not. Did I avoid him? Yes, but that doesn't work in a chronic situation. So I waited for the time when I knew he was going to attack and took him down in a efficiently brutal fashion while he was still woofing and throwing haymakers.
The rapist is responsible for the rape, not the victim. It isn't her "fault" that he is a monster or a failure on her part if he won't listen to reason. The crime and the legal, medical and karmic results of the crime are entirely his. She shouldn't waste a single tear or suffer a moment's remorse over whatever she has to do to stop him with minimum risk to herself.
