I was just curious to see what's your take on art that "causes conflict" or "shock art". Now this sounds very vague so here are a few examples and two categories: Shock-art cases: Mapplethorpe's G-S&M (that I won't link here) R. Mutt's (M. Duchamp) urinal: Immersion (often called PissChrist, that I won't link here) Now those are more "extreme cases" (Yes, I'm aware there's more shocking stuff out here). Those are clearly pieces meant to shock or to defy. Now the second category I could call "art that becomes conflict" Richard Serra's tilted wall: The artist lost in this case, the wall was removed. Buren's Colones: In this case the artist won. Now this may seem random, but I'm just trying to gather thoughts on art and the conflict surrounding it. I thought a few examples divided into two kinds of polemics could help. Street art also comes to my mind when we mention the whole conflictual art theme. So yeah, basically what's your take on avant-garde, shock-art, cultural conflicts surrounding certain art pieces, etc.
