I think it's crucial whether you actually could hurt or not an opponent?
You are right Carsten, definitely it is. My question about performing aikido techniques was a little tricky. I do not have problem with understanding Morihei Ueshiba's art. It is simply not about throwing people. All the techniques, he selected, serve absolutely different purpose. Today, in all the dojos, they are trying hard to adopt them for some kind of entertainment, I presume. Unfortunately, it doesn't work without partners' cooperation.
And, Morihei Ueshiba's art is a martial art. The best and most unique. It is about killing people in the blink of an eye. Practice supposed to be based on judo development for safety.
