Think of it this way - It's the same thing if Americans developed their own Krav Maga and called it Krev Magu. A simple mispronunciation of the Hebrew word. Would that have been OK?
If it's not claiming to be the Israeli system, then yes. It's an ugly name, but so are some other legit ones.
Not quite. The rest of the Jujutsu Ryus are more real life combat styles, designed for killing and self defense, so competitions without diluted rules are too dangerous. Judo was a competitive synthesis. It was designed with full speed grappling in mind, and therefore safer to practice under full speed, full intent situations. Plus Judo had enough exclusive techniques and moves added to its arsenal. If BJJ came from Jujutsu, it wouldn't have looked the same as it does now, and it would likely have a different approach to the competitive aspect.
Er... are you seriously trying to tell me, of all people, what the different Japanese Jujutsu Ryu-ha are about? Really? Poor choice, mate.... oh, and no, that's not correct. At all. In anything you said (save that BJJ came from, in part, Japanese Jujutsu, in particular, early Judo).
That would depend on your definition of the word "little". His point about distance management is really the core of the issue. Learning competition style BJJ might prove more detrimental than helpful in self defense. In a competition, the competitors simply grab each other's lapels and begin careful negotiating of position, but what if someone if launching himself at you with a baseball bat? Ask him to grab your shirt?
I define "little" as "small", "less than big", "not a lot"... you have a different definition? Distance management is also the core of sporting success, just a different form of distance management (which is part of what I was talking about when I said I wasn't impressed with the way they were describing things... there's a lot they don't get, based on that clip... and everything else I've seen. Very good technicians, absolutely, but that's not the same thing).
Oh, and you're really talking to the wrong person if you think you're educating me about the differences between sporting methodology and non-sporting/self defence methodology... and your examples are more strawmen than anything else.
Self defense forces you to bring a completely different contextual approach to your combat sport. it's not just whether he's armed, but the environment in which you're fighting. The width of the space you're in, the type of ground you're standing on, the emotional context of the encounter, the number of people you're facing etc.
Yeah.... you've really misjudged who you're addressing with those comments.
There was a very interesting example of that in the now canceled TV show "human weapon". In the Krav Maga episode, the host Jason Chambers is in Israel and is asked to defend against a knife attack. The knife isn't real and can't hurt him, so it's OK to do it at full speed. Chambers is a rather successful MMA fighter and a BJJ black belt, but in that simulation, he is stabbed multiple times in about 3 seconds into the simulation. With all his combat sport training, he didn't have a clue on how to stop it. And more than anything, THAT is the concern when picking a school for self defense. What will they work with you on?
Okay. Of course, Koryu Jujutsu dealing with weapon defence isn't the same thing either....
Fair enough. I thought it was black, but OK. Still, purple belt is above blue, and according to the Gracies, finishing blue belt means you're street ready and are able to defend yourself against a full-on knife attack.
Ha! Nah, I've seen their knife defence... and I really doubt they'd say that anyone, at any level, is necessarily "able to defend yourself against a full-on knife attack". Anyone who's spent any time dealing with actual knife attacks doesn't say such things.
Plus, Chambers learns BJJ at "10th planet Jiu Jitsu", which prepares students specifically for submission grappling tournaments and MMA, and Chambers does have quite the MMA record. I doubt that he would have been able to repel a knife attack even at black belt.
And your training is in....?
To be clear, that's not an attack, it's a comment on the realities of dealing with knife assaults, and the fact that even black belts in anything will have one hell of a time "repelling" a knife attack... so is your training better? If so, how so?
