While I fear empowered censors more than the effects of such "art," we should at least have the honesty to admit that such "art" expresses the worst of humanity. I'm not even 30 yet, and quite frankly I've grown sick of the self-assured, hipster posers who think this trash is edgy and avant-garde.
Exactly what I have been saying, and it's actually even worse.
When classified as art, these works will bring down the status of those art that actually require good senses and rigor (mathematics, physics, paintings, programs, inventions).
Furthermore, these "arts" may make people so annoyed that they start to regard less of freedom of expression. In the end the rights to say what is important (as in "Galileo") become compromised, together with these other rights (the rights to say "I got a needle in my penis").
