I get your frustration - but don't you think that others on this same forum are just as frustrated with IP /IS proponents as they make a lot of claims without being able to back it up with anything else but "it has to be felt" ? Or how about the IS / IP proponents that dismiss almost every teacher in the world because they do not have it or show it? Names have been mentioned or hinted at that had a major influence on the spreading of Aikido - but now we are suppose to accept that they did not understand it or did not even learn anything from the founder? And this comes from people who have never seen or met the founder, let alone train with him ! How frustrating do you think that is?
I could easily go on and on about the frustrations that are at times - but too often - created by the IP / IS proponents. It drives good people away from what otherwise could be an interesting topic to discuss.
I, for one, have never made a comment about anyone specific "not having it", as for general comments - well, I've felt almost all of the major players.
I've spoken to many, many students of the founder who stated themselves in no uncertain terms that they didn't understand what was going on or how the founder did what he did, take that as you will. It's also documented in many public written interviews.
I know that it's frusturating, but a large part of the discussion, like Stan Pranin's Iwama discussion, is predicated on the argument that something went wrong in the transmission. Agree or not, it's hard to deny the fact that a strong argument for that can and has been made - Stan Pranin's body of work alone supports it.
Frustrated because someone hasn't met the founder? Sounds like you're making a "it has to be felt" argument to me.
Of course, the people becoming "frustrated" haven't met or trained with the founder either, so they have no more basis for their opinion than anybody else, if you follow that argument.
