I am sure this is blown way out of proportion. I am sure Prof Alonso is not aware of this. I am sure he doesn't want this "bull sheet" on the internet. But with respect to calling out other black belts ... I think it is not cool. If you want a friendly match .. call him up. If you are angry ... well act like an adult and keep it to your self. Most the people I respect in the BJJ community (Marcello being one of these) are people who have passion for the sport for the art and for the lifestyle of BJJ.
