They’re not just chucking peanuts at black people at the RNC:

An unscripted moment happened late this afternoon that caused the assembled mainstream media to turn away in the hope that it would disappear. As I was standing in line for a sandwich next to an Italian and a Puerto Rican correspondent, a controversy was unfolding on the floor. The RonPaulites, whose furious devotion to a single idea have made them the Ellen Jamesians of the right, were protesting a decision by RNC officials not to seat members of the Maine delegation, which was split between Paul and Romney supporters following rule changes made just prior to the convention. There were energetic shouts of “Aye!” and “Nay!” as a Puerto Rican party functionary—Zoraida Fonalledas, the chairwoman of the Committee on Permanent Organization—took her turn at the main-stage lectern. As she began speaking in her accented English, some in the crowd started shouting “U.S.A.! U.S.A.!”

This poor woman.  Watch as her own party shouts "USA!" because she is Puerto Rican.

Fox News Latino reported:

A visibly upset Zoraida Fonalledas, Chairwomen of the Committee on Permanent Organization, was greeted by chants of "USA, USA, USA" when RNC Chairman Reince Priebus introduced her to the convention crowd. The chants kept coming until Priebus stepped back up to the podium and told the delegates to let Fonalledas take care of her business. Just a little bit awkward.
