Should Joe Cortez be banned from being a ref?

It seemed like maidnea was fighting Kahn and the ref, It was very obvious the ref was very pro Kahn. He would not let Maindena fight his fight and who ever heard of the ref taking a point for being elbowed? Here's what yahoo sports said about it."Maidana (29-2) was hurt by a point deduction by referee Joe Cortez in the fifth round, apparently for throwing an elbow at Cortez in frustration when the referee broke a clinch" Maidena was robbed and Coretz should loose his ref license.
