very true johnny boy, bjj is an amzing style and i can name a few non-brazilians who in fact are also excellent fighters. why train in anti-grappling and such, as in karate for example, when you can understand how grappling works. if you train in grappling you will learn the set-ups for takedowns and than you will be able to predict a takedown and than you will have the training(bjj) to prevent the takedown from happening. the bottom line is ,if you learn how grappling works and learn a minimal amount of it than you will be better equipped to defend against it.
