Agree, he's very well spoken and as such, had a very bipartisan view on the whole deal. Being a traditional martial artist, getting your black belt these days merely means you've spent the time learning the techniques to get you to that rank. For most traditional styles, it's taken on a sense of character development and disciplined attitude more than having the ability to be a badass. Now, for the differences between BJJ and 10P, that can take a few different points of view. You can argue that 10P isn't BJJ because we don't claim to be BJJ, but if you look at the lineage, you can't deny that our origins stem from BJJ. Look at all the styles that are closely related, but have those differences that make them unique. 10p is unique in that it ONLY does nogi; whereas BJJ can do both, but only recognizes rank in the gi. BJJ is 10P and 10P is BJJ, just depends on how you look at it...different mindset for how one trains means there will be different ways to perform techniques (grips for example and how techniques have to be executed differently due to the loss of a gi).
I train both because I enjoy both. I love nogi because it has less restrictions and it plays well to my game. I love the gi because I'm lazy and don't like to workout. =)
