Well, after having some internet issues for the last few days, this is a lovely thing to come back to...
Without going through everything I've seen here (which would be a gigantic post, even by my standards...), there's a few things to cover, either because I said I would, or because it's just annoying me.
First, Alex, when I asked what "acujutsu" was, you said it was pressure points as used in acupuncture, but as a martial art, and didn't know a better term. Frankly, kid, that just shows that you have no clue, and have never really learnt a thing about the subject. "Acu", from "acupressure/acupuncture", is a Western (English) term, not an Asian one (in fact, acupuncture in Chinese is zhen jiu), so really shouldn't be combined with a Japanese suffix (jutsu, meaning "practical art")... you might as well say you train in "hitjutsu", or "kickjutsu". As to the idea/concept of striking/fighting with the use of pressure points, that's commonly referred to as Kyushojutsu, although that can have other meanings, and other terms can be used (obviously such terms aren't used outside of Japanese arts... but as you used a Japanese suffix, that's probably your best fit. Other than that, there's Dim Mak that's pretty commonly known as well). Really, though, it's just an approach to targeting, in the end (there are different approaches, but commonly, it's just a sense of where to hit).
Next, with the idea of killing with a single hit to the thigh or upper arm, well, I'm going to say yes, it is possible. Very possible. Catch is, though, it's not really possible the way it's been described. The only way you can do it is with a knife, or a machete, or a gunshot... anything that'll let you attack the femoral or brachial arteries (respectively), really. But I really don't think that's what you meant, so try to avoid using this as basis for your delusional ideas on martial arts effectiveness. You're really way off in huge ways.
In the other thread you talk about breaking an arm with a kick, again, yeah, it's possible. Catch is, though, it requires quite a specific set up in the first place. The reason it can't really be done the way you're suggesting (against an arm held out from the body, whether as a punch/strike, holding a weapon, or some other similar way) is that there is no bracing at the end of the arm, so once you contact it, you push it away. In order to break an arm with a kick, you need to brace both ends so that it can't move very far, and have space under the section of the arm that you're kicking. Get someone on the ground, have their wrist up on the curb on the side of the street and stomp down, you could potentially break it (well, I say "you", but I'm speaking of the generic "you" here... from watching your video, as well as your older sparring ones, your knife one, and more, I doubt that you could do much more than a bruise....). But your way? Not likely, son.
Finally, language... look, I love words. I love the feel of them, the taste of them, the way they can be used to shape constructs and concepts, the way they can show the way a mind works, and the way they can express emotions and logic all at the same time. That said, I do try to limit myself to words that I know the meaning and usage of. You don't. You commonly misuse many terms, two of the biggest being your constant misuse of the word "oft" when the proper usage would be "often", as well as your incredibly insistent misuse of "opine" when you mean "opinion". If you wish to use such words, you need to look to the actual grammar that matches it, or, probably safer so you're understood properly, just use the right word.
Right, that should do for now.
