Another Freedom Forum article by the same author raises questions about the limits of legally tolerable offensiveness in public musical performances. The article describes and discusses two 2001 incidents, one in Massachusetts, one in Michigan, where words and actions by musicians led in one case to the halting of the performance and in the other to criminal charges being filed.

It is common for some, sometimes many, people to find a particular creative work offensive. A notorious example of this was “Piss Christ,” a piece by photographer Andres Serrano first exhibited in 1988. Serrano had received financial support for his work from the U.S. government’s National Endowment for the Arts. Outrage over the work was expressed on the floor of the U.S. Senate. The artist’s NEA funding was cancelled, the NEA itself suffered cuts in its appropriations, and Congress passed legislation requiring the NEA to take into account in its funding decisions “general standards of decency and respect for the diverse beliefs and values of the American public.” A series of court cases followed challenging the government’s right to put such restrictions on funding for the arts. Are such restrictions a form of censorship or not? A site created by a faculty member at California State University, Long Beach is a gateway to detailed exploration of the topic.

Here's a 1997 statement from the American Academy of Pediatrics on the social impact of violence in music and what, if anything, government should do about it.
