The notion that art has a political function is a hold-over from the Hitler and Stalin years, when overt, unsubtle propagandizing was at its height. The notion that art is meant to unsettle the comfortable bourgeoisie is mainly a product of the juvenile and narcissistic 60s.
Indeed, the notion that art is a "personal statement" is a modern and, I feel, vain concept. However, it does fit well with the desire for instant celebrity and fame: "It's all about me."
In support of Free Speech, I post two infamous, blasphemous and hideous examples of recent "art." What do you think? I think they are high-school level attention-seeking and tasteless examples of adolescent rebellion against the grown-ups. But Free Speech protects jerks - as it should. Riots? No. Sadness? Yes. And hey - the "controversy" fills the galleries. Mind you, the American newspapers have no problem with these forms of "personal expression" - because they know the Christians won't behead them. There happens to be a little item that says "forgive us our trespasses, as we forgive those who trespass against us..."
The first is "Piss Christ."
