I agree with Lynn's post totally.
Also, it may be important not to forget that Ueshiba M. originally trained in jujutsu and things of the sort to become strong, enabling him to protect his loved ones.
Anyone can preach universal peace and harmony, but if we can't support our claims with the tools necessary to make it reality then we are not only giving a false message to others, but we are also deluding ourselves.
Ueshiba M. could have talked the talk because he could also walk the walk if the situation arose.
Just 2 cents
