Offensive=Art ?

Artist Paul McCarthy recently made a giant inflatable dog turd sculpture. Why is this art? Is this art simply because it offends the sensibilities of people who do not want to have a giant inflatable dog turd in their face? It also proved to be a safety hazard when it blew away from the Swiss museum it was at in a storm and ended up in the yard of a children's home. I don't consider this to be art. What does this make me think about? How does this make me consider the piece? It's a giant inflatable shit for crying out loud! Just because something is offensive should not mean it is automatically art.
