If you don't like someones art, move on. You have no right to be offended. I believe in freedom of speech and people who complain for censorship are scumbags.
The second half of this I agree with. There are very few (I won't say none, but I'm hard-pressed to find one) ideas which should actually not be permitted to be aired.
But the second sentence makes no sense. Freedom of speech is the right to say something even if it offends other people -- the implication being that people absolutely will get offended by it, that your message may well be recognized by many people as being offensive.
