It's just a fucking piece of paper. 
Yes it is just a piece of paper!...thanks Deicide for pointing this out to Muscle....it's the government that guarantees whats written on that piece of paper, hence, the government is giving you freedom, not the constitution..there are many countuies with constitutions but the governments ignore it and treats their people like dirt......
also the U.S. government is protecting your ungrateful ass from terrorists and other countries who would destroy us if they could because they are jealous or our freedom and prosperity....I agree with one of your points, that America cannot be occupied, but a small group of terrorists or a hostile foreign power could set off a nuclear weapon on our soil, or poison our food supply, or even set off a biological weapon......the government protects us (you included) from all of these, and protects your rights so that ingrates like you have free speech to do nothing but criticize the hand that feeds you....
Not to mention u didn't address my point as to what would happen to your sorry ungrateful ass if you opened your big mouth in places like Russia, China, and Saudi Arabia and criticized the goverment....your ass would be in a dungeon right now sucking the dicks of the guards and getting ass-fucked with no lubricant
