to much harmony while training makes us too "soft" outside. My 15 years old nephew (not doing any MA) was able to make "a tekagami pin"
I was just grapping his wrist, he did it somehow and my body was ready to take an ukemi...I don't think that any other Martial artist would allow this.
To much harmony, being ready to fall and "telegraphed" attacks-techniques makes aikido look fake, feel fake and ineffective.
"No touch throw", I don't believe that someone could throw me by clapping hands. On the other hand, there was a technique, we trained. While I attacked my sensei full speed, he kneeled and I could not resist to fall over him. He did not touch me, but this is something else...
