Increasingly, to dismiss any popular artistic style is seen as the worst kind of snobbery. And snobbery, it goes without saying, is unacceptable in a diverse and democratic world.
Personally, I see little distinction between an artistic mentality and criminality. You couldn't possibly create a compelling story without some wickedness or some fascination with the disgusting. Being good is a hindrance to a writer.
Everyone likes to hear that their eccentricities and their addictions are simply evidence of their sensitive artistic nature.
