In The New McCarthyism George Monbiot says:
The charge of “anti-Americanism” is itself profoundly anti-American. If the United States does not stand for freedom of thought and speech, for diversity and dissent, then we have been deceived as to the nature of the national project. Were the founding fathers to congregate today to discuss the principles enshrined in their declaration of independence, they would be denounced as “anti-American” and investigated as potential terrorists. Anti-American means today precisely what un-American meant in the 1950s. It is an instrument of dismissal, a means of excluding your critics from rational discourse.
If we are to preserve the progress, pluralism, tolerance and freedom which President Bush claims to be defending, then we must question everything we see and hear. Though we know that governments lie to us in wartime, most people seem to believe that this universal rule applies to every conflict except the current one.
Democracy is sustained not by public trust but by public scepticism. Unless we are prepared to question, to expose, to challenge and to dissent, we conspire in the demise of the system for which our governments are supposed to be fighting.
