Yeh, I would agree with you.
I think philosophy should actually stay out of the dojo. People usually go to do Aikido rather than chat. Only sometimes is it useful/necessary to describe a concept in philosophical terms.
I asked a sensei several weeks back if he thought having an understanding of zen or taosim could improve your aikido. His response was to forget the philosophy and just think of this very moment and nothing else...
To me the philosophical/spiritual aspects spring from the physical (e.g. facing aspects of life/death; coming to terms with your own ego; breaking beyong your conventional approach). So I'd discuss this down the bar, but not when I'm trying to get the most out of training.
P.S. no offence taken, nor would ever be taken!
