RJ, there are a few rabid folks who feed on threads like this, and they lurk below the line.

I was in-country in Vietnam, in 1971-1972, and I honestly never saw a single example of anti-war activity or active/passive resistance to orders. There were no restrictions on music that I ever saw or heard of, and songs like Universal Soldier were often heard on AFVN (Armed Forces Vietnam) radio.

I'm not sure what you are hearing, and from whom, but there really has been no "removal of many civil liberties" post-9/11. What there has been is the passage of several laws (called, as a group, the "Patriot Act) that potentially restrict civil liberties. Some of these, like increased serveilance of air travel, have brought us up to (down to?) the level that many other nations have had for a long time. Most others have never been implemented, but we object to them on principle.
