I dont mean to say that Ninpo is better or worse than Aikido. However the point I was trying to make was that Ninpo practioners can throw Aikidoka just in the same way that Aikidoka can throw Ninja's. I have many good friends that study Bujinkan. I was not knocking it in any way.
Refering to Peter Lewis however he is in no position to comment on Ninpo or Aikido having studied neither.
Many Thanks for your input.
