Not exactly. The problem starts when it becomes part of anyone's policy (official or otherwise). The result is that you have a very large section of people who practice "Aikido - The Way of Harmony" who want nothing to do with certain groups because what they do is "not Aikido" because their training includes competition for example. This is regardless of what can be learnt on both sides through openness and sharing.
Well, no art is ever going to be everything to everyone and include all and any methods of training. I think that it is reasonable for leaders of an art to define their vision of what the art does and doesn't encompass, just as it is reasonable for people with different ideas to branch off on their own. But if you branch off on your own with different ideas then it seems kind of odd to want to be included under the old definition. Doesn't that belittle Tomiki's contributions? I would think that you should be proud to be classed separately.
