There's a difference here that's important about what it means to be actively hostile.

Yes, some types of art in general have a hostile face. Some metal, some gangster rap, some pop even.

The difference is that nobody but the most fucked up people is going around forcing it on me. I don't have to fear getting to close to the cover of Mayhem's "Dawn of the Black Hearts". I can ignore it if it's right next to me. Ignoring Swangas is detrimental to my health. Album covers don't amputate my legs when they come to close.
