If some dojo has nothing but throw-puppies doing dives for every poorly-done technique, you're not going to argue that it's real and traditional Aikido, are you?
I would probably agree with you if I saw something like that, however, you and I dont have the right to decide if that is Aikido or not.
There is good and bad everything in the world, Aikido included, and yes Doshu has the ultimate authority, but he is not the only person who does "True Aikido"
Just like aikido is not linear, neither is its transmission. O'sensei is the center and aikido's knowledge radiated outward from that center.
Here is a question for you,
Do you think that O'sensei intended for Aikido to evolve and grow, or that it should remain identical to his own?
