OK, I've read through, a few observations. First, the FOX news bit. Its really no worse than any of the rest of the 24/7 news channels. They're all biased. The media in the US donated 9 times to 1 to the democrat party. Information is a dangerous thing and theres still a lot to be had by controlling it, the internet hasn't been able to stop that. So please, endavor to find information from several widely varying sources.
Next, Bush isn't all bad. I tend to disagree with him, and I didn't vote for him. But I'm sick and tired of all these attacks on him for things that aren't his fault. Hes not evil, hes not a moron, but what he thinks will fix things differ fundamentally from my ideas. It really upsets me when our media more or less publicly insults the president. Disagreeing with him is fine, but if you hurl insults at him constantly the rest of the world starts to belive it. They're embarassing us in front of the world, for ratings.
An example; people blame him for the hurricanes. Its completely retarded. Its a state and local responsibilty, and it always has been. The FEMA exists to supplement state efforts, after they request help. Our retarded govenor (D)Blanco tried to play politics and not ask for help until it was too late. I was hit by hurricane Rita, and I still believe this.
Next, why are americans, in general, so apathetic to their own system of goverment? Because life is grand. Our lives are so rich and enjoyable that most of us never take the time to follow any of the giant sea of bureocracy. Clearly things are working out well enough that I can still enjoy my life. There is truth to the statement:
The price of freedom is eternal vigilance. - Thomas Jefferson
and because of this it is inevitable that we will slowly let various freedoms slip away slowly, until enough peoples lives suck. When enough people are willing to be shot for an idea, certainly we will have another revolution and restore most of our liberties. And the cycle will repeat. I think I read Jefferson believed the natural cycle of revolution was every 27 years.
Next subject, rights. The most important of which is the right to bear arms, for with it you guarantee your right to defend your freedoms. The 2nd amendment has nothing to do with hunting, its explicit purpose is to insure the people are armed so they may keep their gov't in check and revolt when necessary. This is something the europeans never seemed to grasp, and is a large part in why their attempts at democracy are failing much more swiftly.
Theres no giant conspiracy to take away our rights, politicians do these things because they're misguided into thinking its the right thing to do, pandering for votes, or have found a way to line their own pockets by doing so.
I've talked to people overseas that criticise the US for having different laws from state to state. This is one of the fundamental ideas that make our system great. Decentralization. The federal gov'ts role is limited by the constitution to a common currency, common defense, and regulation of interstate trade. The congress has found massive ways to violate their powers under the regulation of interstate trade, however. All other rights belong to the state, or the people. Which, yes, is vague.
When you move the bulk of legislation to the state and local level, you put it within peoples grasp. Its much easier to feel your making a difference when you make a change that effects a local level. Each state can make laws to suit its citizens best, and each state can experiment with all kinds of laws, the best of which may be noticed by other states and duplicated.
The basic idea behind the whole thing is that all humans are motivated by self-intrest. By spreading out power as much as possible, and putting one power in check by another, we endeavor to use mans self-intrest to keep his peers in line by looking out for himself. Its not perfect, but I believe its the best out of many flawed systems that we have yet seen.
To summarize, plenty of people still care, and it seems slightly more now thanks to the internet. The bulk of the people don't really care and won't until things get worse. Our government was cleverly enough designed to slow down things getting worse quite well.
To the americans, be wary of gov't fixes for any problem, free enterprise has always done so more efficiently. If you're too lazy to pay much attention, either don't elect anyone that tries to increase the gov'ts hand in things, or at the very least don't re-elect anyone.
To all the non americans, you don't really have a lot of room to criticise when you've let your gov't take away your right to defend yourself and your freedoms.
Edit: for clarity, proofread, wow this was long. Also, if I didn't answer the original question, yes plenty of our rights have been eroded, through bad legislation, and worse supreme court decisions. But some of us are still paying attention and care.
