Yeager, you are just a national treasure.
Its not so much that they are directly impeding our rights as Americans, its the government is creating an expansion of its own rights that nobody can check. I'm more worried about the long term effect, since it will be a gradual process before we see any true American liberties impeded.
These things can happen immediately during war time as well, such as the passage of two sedition acts, making any voicing of opinion against the government a crime against the nation. What if the government decided that it disagreed with what the watchdogs (or the femguys as some eloquent individuals refer to them as) were saying? They'd be criminals, and the government would only be getting stronger with the cut in opposition.
Remember Yeager, true Americans heros such as Jefferson, Paine, or Henry were intense critics of the government, and it was their defense for the rights of the people that prevented America from caving to a much stronger government.
Read up on Federalist/Anti-Federalist debates, extremely interesting stuff.
