Great art is always dangerous to someone. So is great science. Popular opinion has a very bad record,picking art of any kind. It reminds me of an old chinese saying "If a thousand people have a ridiculous thought, it's still a ridiculous thought". I'm not saying that this stuff is great art. It's that a pronouncement either way about pornography or art is doomed. We can say with a little more certainty that 90% of what's out there at any given time is worthless,and history has born that out.
