There were three kings, it is written, who traveled from the East bearing gifts of gold, frankincense and myrrh. If you spot their likeness in front of city hall today, however, there's going to be a lawsuit. Religion on the public lawn is unconstitutional. When government tends the grass, the kings check out. Not if the government owns too much of the grass.
Similar things happen on electronic lawns.
Some years ago PBS stations, under pressure from the federal government, which funds them, canceled Death of a Princess. The feds were buttering up Saudi Arabia, whose leaders were offended by the show. Private broadcasters kowtow to the government, too, because Congress nationalized the airwaves in 1927. One radio station came to grief for broadcasting George Carlin's dirty mouth. Another was slammed for refusing to let an author reply to an attack on his anti-Goldwater book.
