I posted here to get an idea of what others have gone through when training two martial arts, and I agree with you about what you say about not caring what other people say about me. However, I also think respect for what others in my club would think about me training in another martial art, is also something I should consider as a Shodan. I'm trying to approach this from all possible angles, and that is why I posted this.
This is weird for me because in BJJ, once you get your BB, this is it. You are the man, no more beating up.
You can show late for warm up, talk with some BB while others do the techniques of the day.
You can awards belts to other people, you do not line with the rest of the belts. You stand in the front of class.
But in your case, being a shodan means you belong to your club and you are not free to do whatever you feel like doing.
