Supporting Antisemitic Entertainers
Question
A number of popular entertainers (e.g. Kanye West) hold rabidly antisemitic views and make no secret of it. Yet their works are still enjoyable.
What is the Halacha when it comes to benefiting from their works? Is it permitted, for example, to listen to and enjoy their songs on the radio, whereas the listener gives them no money (although the radio station pays them)? How about being a fan and telling others that you like their music? How about purchasing something that includes their works, in which each purchase gives them a minute amount of money? How about attending a live show or concert where they receive money from each ticket sold? How about reading a book by an author, living or dead, who is an avowed antisemite, whether the book itself has antisemitic content or not?
