If your artwork doesn't piss off people, it's not art.
Art & Shock are one.
SHOCK is the mechanism art uses to attract attention.
SUBSTANCE (or "craft" or "content") is what rewards the audience's attention.
Art that shocks with no substance is halfway there - but it's not art.
Art with good content but no mechanisms of shock - also isn't art.
