"Oh,what was that?"
"That was the essence and the point of my post mate."
"Oh dear,most people seem to have missed it..."
It was easy to miss, Yannis -- you wrote a big blob of a paragraph that conflates several different ideas, so don't blame your audience for failing to extract "the point" from all that. It takes some effort, but I think that your points, plural, seem to be:
1. I, Yannis, don't like statistics and believe that they are deceptive, useless and misleading when discussing safety and violence.
2. Even where violence is statistically low, the consequences to individuals is high and not mitigated by statistics.
3. The statement that "the world is not so violent" cannot be logically supported by any number of statistics (or, for that matter, personal anecdotes); however, it CAN be legitimately refuted by a single violent incident.
4. Aikido is "a way for one to develope himself physically,mentally and spiritually and to give him the chance to lead a ballanced life and to be in control of his life." All other definitions are null and void.
5. If there were more trained martial artists than non-trained people, fewer people would dare to attack someone.
Is that about right?
