I'm curious where you get the idea that I believe that Bjj is "invincible". I'm in agreement with you that it is very important. Despite the common belief around here, I only discuss Bjj when it pertains to the topic of the thread. I don't interject Bjj when the thread doesn't warrant it. Further, since the majority of my martial arts experience in grappling, that's the perspective I'm coming from. I think the problem is that when something comes from a Bjj or MMA perspective, some traditional stylists have a sort of inferiority complex and feel that the Bjj or MMA practitioner is attacking their style. I've gotten that charge simply by asking why Kung Fu and Karate while engaged in fighting doesn't resemble pre-arranged forms that are supposedly so integral to their system.
And of course comes the childish charge that I simply don't understand traditional styles, which sounds like a snake oil salesman who gives you a tonic that doesn't do what its supposed to do.
Here's what I do understand; I understand that my experiences with traditional martial arts line up perfectly with those Asian martial artists slapping themselves silly on the streets of China. They even line up perfectly with the video of that Karate guy wildly hitting that pimp and knocking him unconscious by pure luck. You really think I don't know why karate guys don't fight like their katas? You really think I don't know why a Taiji master can't stop a simple takedown? You really think I don't know why Wing Chun and Aikido guys came up with that anti-grappling nonsense? You really think I don't understand why Stephen Hayes can't come up with a simple counter to the guard?
I know the answers to all of those questions. I'm simply seeking some honesty, and to date, I have yet to receive any.
That's okay though. It's what I've come to expect from a certain segment of the MA community.
