Really? Nothing? Nothing!
Inoue is attested in this very thread as someone with impeccable character, and I know nothing about him, so I have no reason to doubt that. And I haven't read his book.
Well, yes, nothing. I didn't know either of them well, and neither did you, so arguing about which source is "better" at this point is a little difficult, especially since you haven't read all the sources we're discussing.
Anyway, my point was that I had indeed heard of someone who said that Shioda was interested in "Aiki". I'm not arguing for or against Inoue, just saying that he presented a different viewpoint. As one of the only people who was there full time from the beginning to the end of the Yoshinkan I find that interesting, whether he's mistaken or not.
As for definitions of Aiki - I have never, not once, stated that Aiki is anything even remotely "quasi-religious".
