How did this become an Aikikai issue? There are just as many (more) people outside the Aikikai training this as inside, from what I can tell...
Koichi Tohei, and I'll mention him since you're in a Tohei related lineage, went way outside of Aikido to develop what he's doing - that wasn't a problem for you?
Anyway, I'm not sure that you should judge what Dan is doing by George or Stan - no offense to either of them, that would go double in my case.
The philosophy of self-defense without hurting another, without humiliating someone...to truly take care of oneself at the expense of no one is really at core to me.
I really don't see how anything the IP crowd is doing conflicts with that at all. I've seen more humiliating in regular Aikido - even directly from Koichi Tohei - then I've even seen in that group.
