If a community decides that some conduct is prejudicial to itself, and so decides by numbers sufficient to impose its will upon dissenters, I know of no principle which can stay its hand.
Art at its best draws attention not only to the way things are but also to the way things will be, when the earth is filled with the knowledge of G-D as the waters cover the sea. That remains a surprising hope, and perhaps it will be the artists who are best at conveying both the hope and the surprise.
