The greatest conductors of Wagner have been Jewish: from Hermann Levi (who premiered "˜Parsifal') through Gustav Mahler, Bruno Walter, Otto Klemperer, Georg Solti to today's James Levine and Daniel Barenboim. I suppose, that must say something about the musical qualities. It is for musicians to decide what to play and for audiences to decide whether or not they want to buy tickets. It is not for politicians to decide. Not to play Wagner because he was anti-Semitic is on the same level as not to play Mendelssohn because he was Jewish.
