The shooter - Wade Michael Page - was the vocalist and guitarist of several white power bands. While I will not suggest that music led Page to this hate crime, I do firmly believe and assert that some music teaches people how to hate; it helps people become better at hating and better at being angry. Music and art can plant seeds of anger, self-pity, insecurity, revenge, and pride. Great art plants virtuous seeds that inspires us to think and feel in ways that enrich our experience and foster appreciation for others.
I think it is critical that we own our thoughts and emotions - that we recognize that anger is inherently deceitful and destructive. Art has powerful influence over our thoughts and emotions. We should seek art and entertainment that supports our best self.
