I'll buy that. Not trying to split hairs, but we can't let people believe the Chinese started Aikido and yoga. It's true if we stretch the truth enough, but to that degree we can say Africans did it. Unless it was aliens.
I'm not sure why it would be so horrible to allege a Chinese connection - but one guy
wrote an entire book about it.
Actually, I think that the case for a Chinese influence, even a strong Chinese influence, is pretty overwhelming - but even more interesting, I've been seeing quite a bit of evidence pointing to a direct link between China and Sokaku Takeda (and thereby Morihei Ueshiba) recently, but more on that to come, I think...
