Sure it's Art. Art at it's very nature is "created" to produce an emotional response in people. This response is not always a warm and fuzzy one. This is exactly what this performance has done, just look at all of you that felt obliged to reply. I have no problem with it.
“No man has the right to dictate what other men should perceive, create or produce, but all should be encouraged to reveal themselves, their perceptions and emotions, and to build confidence in the creative spirit.”- Ansel Adams
