I like your open minded point of view. I still go to class and do what's required; I just loathe the tedium of drilling. At open mats and in class I spend time helping new people the same as they helped me. I don't care about being labeled a martial artist, and I think that's what is driving these angry comments. They take it all much more seriously than I do.
I get it. You're a brown belt - at the advanced level you're responsible for your development more than your instructor. As long as you're not pulling people out of regular class or causing a weird mutiny or something, it's not that big of a deal.
At the end of the day, we are just man wrestling. And that's still pretty fun and cool.
