I am no real Wagner lover, but I think he has made some interesting contributions. He has inspired Bruckner and Mahler for example. It is also doubtful, if he himself was so "unjewish" as he would have liked himself to be: Compare his "Liebestod" ("Love death") to Shir ha-Shirim 8,6: "Azza kamavet ahava" ("a love as strong as death", or more romantic: "love is as strong as death"). "Eros and Thanatos" as Freud would have put it: just common human experiences despite all illusions that we have about our uniqueness.
