There is a long list of artists whose behavior cuts against what most minded people would consider honourable or decent behaviour. I'd like to point out we could easily broaden this good question to sports and politics and commerce. There might be some legitimate dividing line when you think about an artist and their art, because it's typically one artist and their music. So i think you might make a stronger case for cancelling an art form or somebody's work because the artists themselves was morally wrong.
