IENNA –  A committee reporting to the UN’s culture organization struck Vienna’s many balls from its list of Austria’s noteworthy traditions on Thursday amid an uproar over one of the annual champagne-laced galas that critics say attracts neo-Nazis from across Europe.  The decision by the Austrian UNESCO Commission was welcomed by those who oppose the one often-criticized ball, staged in part by dueling fraternities including far-right alumni who display saber scars on their cheeks as badges of honor.
