This forum has helped me a lot, and so I hope you will find a lot of benefit from it.
True that we do many things without giving it a second thought, and most times, it really isn't an issue, especially if everyone is having a good time.
But people are different, and its funny how me raising this topic can sound totally irrelevant to someone else, and I respect that too.
While I am sure we do many things in the dojo without knowing the exact meaning or implication, I believe the same could be said about everyday life in America. Examples include Christmas trees, neck ties and the notion of a popularly elected president.
