I guess that was directed at me. I gave two examples, one was a BJJ instructor who no longer teaches publicly because he saw it attracting the wrong crowd. The other was given as an example because he advertises it as teaching BJJ and other arts, if you are new and don't know the difference then this is what you would assume BJJ is.
I could give another example of a place that I went to that trained BJJ and submission grappling. One of the head instructors was just a plain arrogant jerk who liked to sit around and rip on other people/styles. Some of the guys there were very nice and didn't reflect that, others...well, let's just say that birds of a feather.
Am I saying that all BJJ is like that? No, my first example is what I think BJJ schools mostly represent. A very close knit group that helps one another. But, there are bullying places out there just like every other MA.
