This is just the sort of confusion that Mr. Uman is referring to. What you're describing are two hot-headed people 'squaring-off' for a 'fight', two willing combatants. That is not "self defense", its fighting, and that is where most martial arts dojos, schools, or academies make their mistake. They claim to teach "self defense", but what they're really teaching is competitive or tournament style martial arts.
Those who don't understand there are critical differences between the two have either been students of tournament style martial arts or have never actually been in a true self-defense situation, or both.
Self defense is about NOT 'mixing it up' with an opponent or getting involved in a protracted confrontation. The term "opponent" isn't even appropriate, because it implies a competitive nature. A more appropriate term would be 'aggressor' or 'attacker'.
Self defense is not two guys at the bar, one bumps into the other, some words are exchanged, and the two go outside to settle their differences. That's competitive martial arts. The only things at stake are one's pride, bragging rights, perhaps a split lip, some swollen knuckles and loose teeth.
We're talking about getting up for a late night snack and being surprised in your living room by a two time felon who was just released on parole. What is at stake is one's life or serious injury. That's "self defense".
The essence of self defense is to inflict the maximum amount of damage in the shortest amount of time, with the goal of disorienting or, ideally, incapacitating an attacker long enough to remove one's self from danger and get to safety, by running if need be. If the defender has an opportunity to definitively end the confrontation, he takes it, but that opportunity cannot be counted on and often doesn't present itself.
The defender is typically at a serious disadvantage from the start because the defender will likely be caught by surprise and has little or no time to prepare himself psychologically. Brutal tactics like eye gouges are not taught in tournament arts, but in a self defense encounter, you don't care if you rip some guy's cornea off and blind him. Similarly, you don't care if you break bones and shred joint capsules, leaving someone with an injury that could be disabling. In fact, inflicting that sort of injury is highly preferred.
Surviving a self defense enounter may require a psychological ploy or de-escalation techniques, which almost no martial arts schools deal with. Weapons are A-OK, anything literally goes, there are no rules, restrictions, and fairness doesn't exist. You don't "win" a self defense encounter, you "survive" it, and this is where many schools or instructors completely miss the mark.
The two types of combat - competitive and self defense - aren't mutually exclusive, but they are sufficiently different and need to be treated seperately.
