Not sure if you're trolling or you're just this ignorant. I've read two Bruce Lee biographies, read the Tao of Jeet Kune Do and John Little's books several times, read and listened to all the interviews of him, his family and students and watched all the documentaries I could find.
I have seen probably 5 Bruce Lee documentaries and to show you i am not full of it, he would punch within 3 feet in about 5 hundredths of a second, he did one inch punches, where people would fly back 6 feet, he would explode 150 pound heavy bags with kicks and the feathers would fly out everywhere. Are YOU trolling? How the hell could you have read 2 biographies and not know that people were offered movie contracts for beating him in a street fight? It is common knowledge. People would come up to him in Hong Kong or wherever he lived, (this was before he moved to San Francisco where he taught Steve McQueen and Kareem Abdul Jabbar in his martial arts school), and strangers back then would tap their feet in front of him in a certain way that was code for "i want to fight" and Bruce would regularly fight people who challenged him in public and from everything i heard he never lost a fight. He would defeat them within seconds and basically go on with his day. This is not in the U.S.
You are basically saying that Bruce reached a point where he became passive and didn't need to prove himself, that is complete nonsense. Bruce carried guns and became extremely paranoid the last few months of his life, I read that in a playboy feature on his life, he also lost 15 or 20 pounds the last few months of his life and was smoking hash. His death certificate said "sensitivity to hashish and brain swelling."
Regardless of that, Bruce was not a bully but never reached a point where he didn't need to prove himself. Because he took on the entire ancient martial arts community which was at odds with him and Jeet Kun Do and felt threatened by him, he was even more of a target the last few years of his life, especially being that he was going to be the first Asian martial arts or action star to break into the U.S.
"The Art of fighting without fighting" was definitely not him passively avoiding fights, Bruce was a fighter in every sense of the word and never would back down from a fight EVER. From everything I know about him, his philosophy was to only move "WITH" his opponent and REACT to them, as opposed to attacking first and leaving himself open to a counter. It is his own personal philosophy and has nothing to do with him passively avoiding a fight. He said in quotes he would make references to being fluid like water and reacting. That is all he really means in general in his philosophy. If you think that Bruce would ever passively avoid confrontations at ANY point in his life, you don't understand him as a martial artist or philosopher.
The scene in the video you showed me was him outsmarting a bully. He tells the bully, "my style is the art of fighting without fighting" but that has nothing to do with him avoiding a fight with him. That was never Bruce's style. Bruce was cocky and super confident his whole life and never avoided a fight or confrontation. I guess you should read a few more biographies. i read about 10 giant Bruce lee magazines with tons of features and articles. God knows what you read
