Re: Why do some people hate Aikido?
Aikido requires diligent, focused effort to get a grip on intellectually, let alone physically. It has sometimes been frustrating to realize that I may never get to a satisfactory point with either aspect, but by and large I'm enjoying the ride. The validity or invalidity of the art will be the same, regardless of opinions found on internet fori or elsewhere, so while I might have the urge to set others straight, it's not really a central issue for me, and would most often be wasted effort, in any event.
Who was it who said, "Do not seek to become like the masters; seek what they sought"? If enough of this do that, the truth of our actions will up the signal-to-noise ratio for those looking at Aikido from the outside.
