First off, this thread is not a discussion about comparing TKD to Kajukenbo. It is a discussion about what people think about Kajukenbo. I, as well as many others here, as curious as to what research you've done on Kajukenbo? Have you visited a school? Have you trained in it? Are you going on what you've heard from others? How can anyone say what the art is or isn't unless they've seen it first hand? We have someone on this forum, Mr. Bishop, who studies Kajukenbo. That being said, I think I'd be more inclined to take the word of someone who studies the art, over someone who may/may not have really looked at the art.
As for "cherry picking" techniques. Are you honestly telling us that TKD, since day 1, when it was first thought of, did not do the very same thing? Every single school in the world that teaches TKD, teaches the exact same things? No variations? No additions? Nothing removed? Everything that the founder of TKD used to create the system is taught by everyone?
