Unless you consider the community that makes up the world practice of Aikido to reflect in some way on Aikido itself. Personally, I think the community and practices common therein are Aikido far more than any specific techniques are. If that's true, then you can totally blame Aikido. This story is the rule, not the exception. I mean really, if a given community consistently produces people who aren't prepared to apply what they practice to such a degree that they don't even realize it, I think that can be laid at the feet of that community. Especially when there are communities which consistently produce the opposite. If he said it about boxing, most everyone would assume (and usually accurately) that he never actually learned to box much at all. Since he's saying it about aikido, unfortunately it sounds about right.
