Re: Of self defense
I doubt any accomplished martial artist of any kind would be unaware that their art is capable of causing harm. Over zealousness is a lack of control, control is something a martial artist should be learning.
I also very much disagree that other arts hammer the reasonable force message, with some of the more hard or external arts the whole idea is to smash your opponent to a pulp to save your own life, I dont particularly see the 'reasonable' in that. I would have to say Aikido is one of the arts that you have most control over your force and can actually achieve 'reasonable force'.
