Re: Why so many Haters of Shin Shin Toitsu Aikido?
The last Ki Society seminar I attended in full was by Kataoka Sensei about 8yrs ago, he stated that Aikido isn't a martial art, however grabbing his wrist off an on over the years tells a different story.
I think aikido attracts an interesting subset of the martial art community and Ki Aikido a subset of that. Its not too hard to imagine that a feedback loop of what attracts and keeps students could drive the focus of a dojo/school/style and so the Ki aspect, which is what makes Ki Aikido unique can shift the focus away from 'mainstream' aikido.
Having started in Ki Society and trained around quite a bit in most many other schools of aikido I don't see any style having a monopoly on doing O'Sensei's aikido and those that tend do be doing the best seem to have broken from the mould/constraints of their style somewhat.
As a generalisation its pretty clear that for the rank and file student that the path to martial effectiveness in the short term tends not to be a strength of the Ki Aikido style schools
