I’ve been to his dumpy MMA gym. It’s trash. Nobody who knows MMA trains there. Pathetic 50 year old photos of him with Bruce Lee everywhere like that means anything in 2020. Weak.
Sounds like you are very bitter and have some hurt feelings and resentment. In real life, Guru Dan, as he is often referred to, is held in the highest esteem by everyone in the MMA community and the martial arts world. He has never used his association with Bruce Lee to promote commercial success like many do with other martial arts instructors. Henry Atkins, a very legit and high level Jiu-Jitsu instructor, bases his whole business around the fact that Rickson Gracie was his instructor and who he got his Black Belt from. Many do the same with other well know competitors but never Dan Inosantos. Never has he, himself, promoted any courses or his school based on his association with Bruce Lee or being one of his closest friends and original student of the probably the most famous and admired Martial artist in the world.
Futhermore, Dan, personally, is one of the nicest, humble, down to earth man you can ever have the pleasure and honor to meet. I don't understand the hate and resentment but you can't please everybody. Fortunately you are a very tiny minority. In fact, never have I heard or read anybody say anything negative ever about Dan and your comments here is more of a reflection on you than Inosantos.
