in defense of chylaxin. I think what he is trying to say is that those arts practice as sport dont have the same combat benefits as those arts that practice in real life, And fact is fact, everything does change in a real life situation, I dont dislike people who practice olympic TKD or those who practice any martial art that is a sport. But I do dislike it when they say its a form of self defense when in reality its just for competition. Thats my opinion on it.
