Before you read any further, please listen to this song. Recognize it? Maybe you even had it played at your own wedding or the wedding of someone you care about. Do you like it? Well, if you do, congratulations. You’re a Nazi. That song, most commonly referred to as “Here Comes the Bride” is actually the wedding march from Lohengrin, an opera by German composer Richard Wagner. Wagner was a noted anti-Semite and his music was embraced and promoted by the Nazi Party in 1930s Germany.
The above example is designed to show the absurdity of the guilt by association mindset, the idea that there is no meaningful separation between art and artist.
