Was Richard Wagner an Anti-Semite

Answer 1

Yes. Richard Wagner was very proud of his Anti-Semitism.

Some quotes of his to this effect include:

It is necessary for us to explain the involuntary repugnance we possess for the nature and personality of the Jews … The Jews have never produced a true poet. Heinrich Heine reached the point where he duped himself into a poet, and was rewarded by his versified lies being set to music by our own composers. He was the conscience of Judaism, just as Judaism is the evil conscience of our modern civilization. ~ "Judaism in Music" (1850)

Jewish music is bereft of all expression, characterized by coldness and indifference, triviality and nonsense...There is a harmful influence of Jewry on the morality of the nation. ~ "Judaism in Music" (1850)

It should not be presumed that these people (the Jews), who are so separated from us by their religion, have any right to make our laws. But why blame the Jews? It is we who lack all feeling for our own identity, all sense of honour. ~ 14 November 1878
