Achilles,
You might do better first asking people if they've read the Constitution, which I have. It assists your argument to first ask people if they have, then if they have not, challenge them to read it. When I was in high school, the Constitution was taught as part of American History. I've read it many times since then.
The thing about a Constitution is that it only works when the politicians are held accountable to it all the time,including "your guy" and not just the "other guy" or the next administration that you didn't vote for. Now, the aforementioned terrorism laws were not passed by Obama; they were put in place at the behest of the Bush administration. Did anyone speak up at that time? Some did, and they were considered "unpatriotic". Remember the words of Pastor Neimoller: "First they came for the communists, and I did not speak out—because I was not a communist;
Then they came for the trade unionists, and I did not speak out—because I was not a trade unionist;
Then they came for the Jews, and I did not speak out—because I was not a Jew;
Then they came for me—and there was no one left to speak out."
The time to speak up was when the terrorism laws were being crafted. Obama merely uses laws already in place. But people didn't, because they never imagined the laws could be used against them. They thought it would be "the other guy", you know, Arabs and such. And when an American citizen was jailed without charges under these laws, no one spoke up. The words of Pastor Neimoller and never truer, are they? These are valuable lessons we can learn from.
You are correct; the government is no longer in the hands of the people. But this has been going on since the end of World War Two. We can't pin the blame on any one man or administration. Things are not that simple; they never are. Nothing happens in a vacuum. It first takes a population to allow it, for one thing.
I am glad to see you asking questions. Whether or not we totally agree on all things makes no difference. I, for one, stand up and cheer people such as yourself getting involved and taking a stand. I think we all want to see the best for our country.
Have a nice evening.
