Dan, this is not a proposition that can be refuted or proven physically. It is more an issue of truth in advertising. So I go to push you, can't move you, then I find myself flung across the room, big deal. Doesn't make it Aikido. The fact that it is pretty cool, and you've attracted some higher-level Aikido people to train with you, and they say it has opened doors for them, revived their practice, doesn't make it Aikido. Doesn't mean it has anything to do with Ueshiba.
On the other hand, if you follow Stan's logic
, just because you call it Aikido and were taught by people calling it Aikido doesn't mean that it has anything to do with Ueshiba (at least, that particular Ueshiba) either...
Physics is physics, whether I learned it from Newton or not - and if it's not physics then it isn't physics, even if I learned it directly from Newton's son.
Before anybody blows an artery - I'm not arguing that this is the case, but the logic certainly applies.
