Interesting that you seem to be making a case for AH’s anti-Semitism to have developed later in his life rather than something he believed in as a teenager.
Of course, there was another Jewish person involved in AH’s family life, the physician Dr. Bloch:
Are you implying that RW’s anti-Semitism did not apply to the arts? That is surely not impossible, but what exactly are you referencing as a source?
Ironically, AH’s anti-Semitism seemed to have taken a back seat to his love of Wagner’s music, in that he had nothing negative to say about Mahler’s conducting of Wagner’s works.
Plus, AH and GM happened to be in the same place at the same time on May 8, 1906, when AH attended a performance of T+O at the Vienna Opera with Mahler conducting. It is doubly ironic for me, in that May 8 is my birthday….
