A desire for security can lead to a loss of freedom. On the one hand, people fear government power. Public debate over the Patriot Act and wiretapping exemplify this. There are other ways to lose freedom. Political correctness or fear of reprisals can lead to censorship, whether it is government sponsored or not.
So here's where we are: we have a first amendment guaranteeing freedom of speech and separation of church and state. That means so-called artists can make art of a crucifix soaking in urine and of holy Christian images made of animal dung and no one can stop them. That means bookstores of brick and on-line can sell Mein Kampf and the vilest writings of Hitler's lackeys. These horrible excrescences are protected and the media screams bloody murder if anyone tries to protect the sacred in Christianity and Judaism from the most putrid attacks.
But the media censors itself about the cartoons mocking the prophet of a religion many of whose adherents want to destroy our country and our way of life. We will fight to the death to protect the artists who create Piss Christ, but we'll also fight to the death to protect the feelings of the people who hate us and kill our children. We have surrendered our free expression to people who are at war with us. They kill us in the name of a religion and we bow and scrape to that religion while letting people dump on Christianity and Judaism.
