A lot of what passes for "art" these days is really little more than the making of crude statements using outrage and shock to draw attention to "work" (read statements) or "artists" that otherwise would never have received any attention. The use of rape to do so, and even by a social commentator like Zapiro using it in his cartoons, decontextualizes the real and serious issue of rape, turning it into a cheap political football. And even in this context the graphic depiction of rape is simply distasteful. I am sure there are better ways to get the same message across, although the "artist" might not receive the same undeserved attention.
