Re: Poll: Does aikido contain any physical principles not present in any other budo?
Just a reminder:
The question was "not present in any other budo". It is not ask about the majority. So if you think, you can find ONE budo discipline, teaching the same principle - maybe in a different way, the answer should be "NO".
And cage fight is NOT budo. There is no DO and 'though they are fighting seriously, it is more for entertainment, than 'martial' or 'protective', however you interprete BU.
