While I don't fully agree, John P, there's definitely something in what you say. I remember watching a documentary about a gallery which decided to some work by a prominent artist, that a right wing group wanted to ban because they felt it was pornographic. While the right-wingers eventually lost the case in court, a spokesman afterwards said it didn't matter, because they had won in practice: few if any galleries would be prepared to undertake such a long drawn out and expensive court case in future and would stick to 'safer' exhibitions.
