Granted, there is some lame aikido in the world, but this is a gross exaggeration. There are far too many truly excellent aikido practitioners in the world for this to possibly be true.
Sorry, it's just obvious.
Believe me, I got plenty of good from "standard aikido" over the many years I trained before I felt the power from Minoru Akuzawa and Dan Harden. And while my aikido never failed me when I needed it, I had to admit, after all, that it was much closer to a type of jujutsu than to the type of aiki displayed by Morihei Ueshiba, Yukiyoshi Sagawa and Kodo Horikawa.
It has, indeed, been "hidden in plain sight."
Best to you.
