When you have Al Sharpton calling the NBA racist because it *didn't* suspend Arenas, and numerous non-sports outlets calling for his suspension, it's no surprise that Stern would act.
When a piece of human excrement, race baiter, and a collossal poverty pimp like sharpton speaks, everybody should ignore him or shout him down.  
I sincerely hope Stern ignored him.  I agree with what was said about Delonte.  I'm sorry....I see little difference.  Delonte is lucky to be playing.  I'll bet Arenas doesn't see the court for at least a year.
