Took the words right out of my head. The two tend to crossover in the grey areas.
Do they?
I view a "fight" as a failed attempt at self-defense.
Self-defense does not necessarily involve physical contact, but there are even more differences than just that.
From what I've gathered from my years in training from various instructors is that "fights" should and can be avoided. If/When attacked or even threatened it is at that point where self-defense takes place. However, when one's self-defense fails a situation can then become a fight becuase at that point your opponent has telegraphed your intention.
With a fight, there is posturing and preparation; almost a competitive sense about it. You "put up your dukes" and even before that at least one, if not both, members involved in the fight have announced that there indeed will be one.
There is no "announcing" where self-defense is concerned as that is a "telegraph." The last thing we want our attacker/opponent to know is that a whole lot of nasty is coming their way.
In terms of self-defense, I don't want my opponent to know my plans. I don't want them to know I'm going to hit them. My actions are quick, decisive, brutal, and intended to ensure I leave in one piece. It's not about bragging rights.
Fights involve ego. Self-Defense is ...well...just that. It's not about proving anything, it's about self preservation.
Example
Scenario: Mall parking lot, guy in car cuts right in front of you trying to get a parking space you're pullling into. As a result he hits the left front of your vehicle. The man gets out of his car in a threating manner yelling obscenities and cursing your heritage.
Fight: You retaliate verbally as well, citing that his family tree has no branches. He gets even more angry and starts to move toward you. You start moving closer to him continuing the exchange of insults and threats. As you come closer together you put up your dukes and before you know it you're both swingin'....
Self-Defense: You remain calm and instead of returning insults you start to dial 911 so that the police can take a report for your insurance company.
(a) the fellow continues to hurl insults but stays by his vehicle. You watch him warily but do not return any insults. Instead, you simply say the police are on the way and they will sort it out.
(b) the fellow takes offense to you calling the police and either (1) gets back in the car and flees because he has warrants, no insurance, whatever or (2) Comes at you aggressively, continueing to make threats. You warn him to calm down and stay away from you. You suggest he stay by his car until the police arrive. He does not, so you have to find another option. You can get back in your car and lock the doors. Or, if he closes the distance quickly and you don't think that's an option you can strike hard and fast when he's in range. You do NOT announce that you're about to break him off a piece, you just DO it. You don't get into a fighting stance and wait, any maneuvers you execute have a definate purpose related to putting the fellow down. You DON'T wait for them to swing either. They've made thier intention clear so at that point it's you or him. He may be thinking "I'm gonna punch this sucka's head off" but you're thinking "if he takes one more step he's gonna need surgery to repair his ACL."
Not sure I conveyed my point well or not....but maybe some will get the gist of it. LOL
