Because the OP didn't mention whether his Kempo instructor taught him how to fight or not.
To answer this question. No, not really. They said it was for self-defense but it was like, stand here and I'm going to show you how the technique is applied. There was no non-compliant application of the technique.
From all the back and forth going on here. There are two schools of thought regarding legitimacy.
1. The person is more concerned with how it is applied and whether will it work in a fight
2. The other is regarding the history of the martial art and the techniques taught.
This is my viewpoint. When I was younger it was about could this help me in a fight. Now that I am older and in all honesty in my almost 30 years after taking Kung Fu, I have never once been in a fight or even been in a situation where I would get into one. So for me, it comes down to this. Legitimacy for me is the following:
1. Was what was taught correct?
2. Was the person of said rank, knowledgeable enough to even teach at that rank, or were they pulling it out of their ***?
3. Their integrity, are they teaching it with the intent of helping someone or is it just for the money?
I know in regards to what I said about not ever getting into a fight as I got older, I guess it could happen one day but what are honestly the chances if it hasn't happened in almost 30 years? Sure, I got into fights when I was younger, but I'm 48 now and I've grown up since then and there are other ways to resolve conflict.
The point I am trying to make is if a person isn't qualified to teach someone, should they be teaching it? In regards to Olaf Simon, he wasn't fully qualified to teach what he was teaching. I don't care that he was a skilled fighter. Yes, he learned some Kenpo, and the stuff he learned, he could teach, it was the other stuff that he was pretty much pulling out of his *** and passing it off as higher levels of Kenpo.
