In what appears to be a direct dig at Rener Gracie for "selling internet belts," Robert Drysdale responds to a comment Royler Gracie made on his personal Facebook account (not a fan page).
When you are part of a family as large as the Gracies, there is bound to be friction from time to time. There's always been a bit of contention over cross-training in other martial arts, the way schools are run, the way belts are awarded and any number of other perceived slights to the family name. Royce Gracie has even gone so far as to criticize the younger generation of the family for their losses in MMA.
