I never bother about composers personal morality, but I will never listen to composers' works who were sympathetic to Nazi Germany, Vichy France, Mussolini's Italy, or were enthusiastic toadies under Stalin.
Bothering about it - or about what it is said to be / have been - is one thing but allowing such concerns to discourage listening to any of their music is quite another; do I want to stop listening to Wagner or Schmitt for this reason? - no, I don't. The behaviour of both (especially the former) has been questionable and questioned, but the absence of any evidence of it in the former's
Tristan und Isolde and
Götterdämmerung or the latter's Piano Quintet (one of the finest ever written for the medium, to my mind) gives me no reason to cold shoulder them as composers - which nevertheless does not mean that I can or do overlook their personæ or conduct...
