What does that have to do with it?
Do I really have to go through this?
I said "Because if it's a specific culture - say, the culture of O-Sensei's personal dojo, then you ain't got it."
You said "Which personal dojo?"
I said "The only one that he had after 1942 was Iwama."
You said "So...they weren't practicing Aikido at the Asahi Shimbun or at the Kobukan?"
I said "Those were before 1942."
Which was answering your question.
Howso? What is different about Saotome Sensei's etiquette exactly?
Never heard anybody clap when they bow into class at Hombu (for one example). There are others, none of which are important, IMO.
