They should ban Wagner then have a huge rally where they burn books written by Germans. What a GREAT idea!
Wagner isn't banned in Israel; you can buy his music in any CD store and play it at home. Israeli orchestras do not publicly perform Wagner's music because, whenever they have announced that they would, there were public protests; but there is no legal ban on their doing so. (And, as the article notes, at least twice Israeli orchestras DID publicly perform Wagner's music, albeit as unpublicized encores, and suffered no repercussions.)
