Well the world is full of imperfect human beings and I wouldn't like to place Burns on any kind of spectrum thereof. Picasso was a notorious philanderer, Mozart loved poo-poo jokes and lots of smacky-botty, Bach spent time in jail and Beethoven lived in squalor and indulged in repressive behaviour towards his nephew. Being less than perfect meself, I can live with a' that (as Robbie might have said but probably didn't). I draw the line at artists who showed overt racism or antisemitism such as Wagner (a detestable antisemite) or Karajan (card-carrying Nazi), etc., and avoid their art. It's all just a very personal thing.
