I find it extremely foolish to renounce an artist's work because of the life that artist has led, and miss out on it, or, in the worst case, encourage others to miss out. Knowing the artist helps us understand the work, but, at the moment of creation, the artist—just like us when we consume his work—is situated in another realm. The world of creation is, by the way, a place of stricter moral rigor than life itself. Vargas Llosa, for example, so painfully anti-Catalan, wrote some of the best essays you will find on the subject.Strap.
