Asking for info about what happened... a fight? a roll? a demo? is not attacking Dan.
Well there are people out there who train with Dan openly and have no problem with that. Others may have issues with political or personal conflicts in openly stating they are training in this methodology. The group they are affiliated with may disapprove. We all know of the disharmony just within the Aikido world.
As far as the BJJ champion is concerned, do you really think a professional athlete, who makes their living on winning fights would want to openly reveal their "Secret training method" to the world?? I think not.
You also have some willing to put money up to show you whats its all about. That's how compelling the training is. We all came to meet Dan with an open mind. What ever doubts there were previously were wiped out from the first contact. To quote William Gleason Sensei "This IS Aikido".
