Diaz deserves to be pulled from the fight right now or as late as after the first prelim starts and join the UFC farewell boat that just departed taking fighters way more respectiful and professional than him.
The difference between the education level in the 1st and 3rd worlds lies in law enforcement. You don't impose the rules, you don't punish, you don't apply fines that's what you get. A rogue, arrogant element, bypassing real athletes and carrying along a legion of fans that forgot the meaning of "professional sport".
Funny some think adding lower weight classes or women to the event are the real bad moves to the business, but keeping a low life scum like Diaz around, spreading his venon is a must.
