All rights have reasonable limits. The right to bear arms does not include a right to own a nuclear weapon. The right to free exercise of religion does not include a right to ritualistic child sacrifice. The right to free expression in art should not include a right to film yourself having an abortion; neither should it include a right to use feces, urine or any other bodily fluid in public, nor should it include a right to engage in sex acts before live audiences.The public has an interest in preventing the pollution of its artistic culture -- and the law should reflect that interest. As for the "boundary-pushing" performance "artists," those "artists" who cannot work within the bounds of common decency should find another line of work. Shakespeare somehow worked within the strict guidelines of his time; so did da Vinci, and so did Beethoven, Brahms, Bach and Mozart. If Aliza Shvarts, Robert Mapplethorpe, Andres Serrano and other "artists" cannot do the same, they ought to consider going into the demolition business. After all, they're so good at destroying worthwhile ideas and limits already.
