From the moment you start saying "It's part of what I am, I can't change it", you make the situation non negotiable.

It's a crucial situation because joining a dojo is a commitment to a learning process, and implicitly you accept to be changed by it, and most probably in unexpected ways.
On one side there is your personal integrity that will dictate to put an end to the experiment if you consider it goes beyond the acceptable, but sometimes the value of the experiment can also lie in pushing the envelope. On the subject there are very interesting pages in Ellis Amdur's book Old School, concerning loyalty, commitment and limits.
