First of all, let me just say that I believe Renzo Gracie to be a good man! He is a classy guy, who cares about the sport, and doesn't wish to hurt people.
However, some of his students on here (you know who you are) act in a classless manor when trying to "defend" your great teacher. You are reduced to insulting at, cursing at, and sometimes even threatening the person you feel has disrespected Renzo.
I'd be willing to bet that if Renzo was aware of this, he'd be inclined to encourage his students to act in a more respectful way.
