In recent years there has been a ludicrous campaign to try to say that one must not appreciate art by those who are morally sub optimal. One can value and artwork while also accepting that the artist is immoral or even repugnant.
Peter Sellers played an Indian doctor in his song goodness gracious me. He sang a duet with SOphia Loren. A doctor having a romantic liaison with his patient is now viewed as totally unethical. In fact it has been so since the time of Hippocrates. One could not broadcast a song celebrating such a relationship these days. Rowan Atkinson reprised this song with Pixie Lott in recent years. Is it morally wrong to derive pleasure from a song that seems to laud an unethical relationship? The doctor would be struck off or even gaoled nowadays
John Donne performed a marriage on an under age girl. In those days the lawful age of matrimony was 12! These days he would be regarded as an accessory to a heinous crime. In fairness, abbeting such an act is indeed a grave offence against morality. Does this mean we should not appreciate his poesy?
David Niven deflowered a girl aged 15. These days he would be called a paedophile. He was an ephebophile. This girl became pregnant and her baby was aborted which was illegal at the time. Being an aristocrat she managed to have a doctor do it and pretend that it was therapeutic. Should we not enjoy the films that Niven starred in?
