I am a huge fan of David Bowie (may he rest in peace), and want to buy his album The Next Day Extra, because it is a special edition that includes some rare songs.
Unfortunately, it also includes “The Next Day” video, which has been harshly criticised by the American Catholic League, apparently for blasphemous and obscene use of Catholic imagery. I have no intention of ever watching that video, because I believe that it would be a mortal sin.
Is it morally permissable to buy an album that includes such a video? Would it be a grave sin?
