So closed fist is bad?

I find it funny that all the"combatives" guys spend so much time trying to convince people that relying on closed fist striking for self-preservation ALWAYS leads to shattered hands. It is one of their most cherished mantras.

Yet, one of the heroes of the combatives/RBSD guys is now coming out with his latest DVD series and - SURPRISE! - it is all about closed fist striking for the street! LMAO!!!! What is really great is the guy has little training in it (and believe me, it shows in his movement from the promo clip), but that doesn't seem to mean that he thinks he is not a subject matter expert. Sheesh.

I wonder how the RBSD people will spin this.
