There is a lot of disrespect shown towards other martial arts since the big MMA boom. I figure that they don't look at their BJJ or boxing as self defense, but more like how to beat someone up. Good for you beating that guy though. Too bad that they didn't grow from it, but instead harass your school. Respect has always been important in martial arts, but there are so many people just tryng to learn the techniques now instead of the art itself that it is starting to actually degrade what it means to be a martial artist. They'll probably learn down the road though.
