A Brown Belt

The expert. No, you don't have anything on me. I've been in tournaments and combat situations. How would you know what I can and can't do? You are what we call a couch potato martial artist and know absolutely nothing. I thought you would have been at least a black belt. Chuck Norris got a black belt in Tae Kwon Do. But, he continued and learned other forms of fighting. You quit. Winners never quit but quitters never win. Look, I don't like the training methods in traditional schools either. They are part to whole. If I had your stupid attitude, I would say I wasted 5 years in Karate too. But, I learned some valuable things that I've incorporated into my system of Kung Fu. One of my black belts moved away and started taking some classes by a well known artist seen in Black Belt Magazine for decades. He came back after a few years and showed me a couple of things that I was able to incorporate as well. I'm open to things that work. I agree that it is beneficial to learn things that other systems of fighting have. I'm not close minded. But, when you do incorporate other things from other systems, they have to flow properly in your system or you end up causing confusion while fighting. So, I've been careful. As I pointed out, it's critical for most people not to end up on the ground. See, muggers and criminals look for easy targets that look weak and awkward. They look for men or women who walk toe to heal like women in high heels because they are off balanced most of the time easy to knock down or slow to react. So, my first line of defense is to defend quickly and forcefully and get out of there. Kick the knees out. It only takes 7 pounds of pressure on the side of the knee to tear tendons and ligaments. A small child can easily get to the side and kick with 7 pounds of pressure.
Most of the grab hold defenses I learned in karate don't work against stronger opponents. But, I use with my kung fu the person's aggression and strength to gain quick control and snap back hitting them in areas that quickly knock them out like the student I told you about did. But, I also believe in teaching ground techniques as well in case you are taken to the ground. I'm not against any of it. But, there are a few things I learned in karate that fit into my system as well.
Stop trying to say one system is better than the other. The key is how the systems are taught that make the most out of the lessons. You didn't apparently figure that out and quit. You are a quitter. I'm not. i kept learning and you didn't. You live in a make believe bubble watching rigged MMA fights and other nonsense that you think is real. The only real self defense is the ones that actually work in the streets. The rest is entertainment.
