I am continually amazed by the number of people for whom it is not enough for aikido to simply be aikido. Aikido is not for explaining the origin of life and matter -- we have science for that.
Indeed...and this is a subject of another thread, I'm sure, but I'd love if some of those people could answer that question: why do you need aikido to be more than aikido? Of course, their proof-by-definition answer is that all that other stuff IS aikido. This is plainly nonsense, but try telling them that.
