First... in all seriousness, calm down. You're not helping anyone by panicking. Take a deep breath, step away from the media sources, and get ahold of yourself.
After you've done that, do what ever you want. Move if you want to. How hard is it? I don't know, why don't you try getting a passport and getting the ball rolling?
I'm on the fence about this one, because I certainly see how this bill could be used to detain many, many innocent people. However, I am also a big fan of the motto, keep calm and carry on. Don't panic. It cannot and will not help anything for you to lose your head over this or any other issue. I will say that I'm strongly considering relocation, because I feel this country is dangerously close to violating our civil rights as citizens. However, if I do, I will do it peacefully, amicably, and without fear, because it is a matter of preferential belief.
For what it's worth... right now, I see this bill as a tool they may use as leverage to prevent mass protests like the occupy movements. And, while I don't approve of that usage, I'm also not out parading in the streets. My big concern is if this bill is used in conjunction with the SOPA (stop online piracy act, aka censor the internet, aka take away our first amendment) in which case there could be a serious danger and threat to many people who exercise free speech on boards very much like this one.
However, the talks on that bill are strained right now, and there has been a major delay indicated at this point, which is a good sign in my eyes. it means that there are enough people speaking up and creating resistance that it's not just going to pass without some serious editing.
The most important thing to do is to stay calm and rational. You can do what ever you think is in your best interest. I agree that the language used in the NDAA is seriously suspect. However, I will not ever let such a thing shake me into fear, as that is what is really desired from those who pull the strings at the top of the pyramid scheme. The more fear, conflict, and strife, the more the average man loses his perspective and belief in his own strength; the more control is gained by the few who are unshaken. BE unshaken, rather than letting yourself be shaken.
Do you know that you are an infinite being of unimaginable source? Do you know that you are a creation of your own imagination? Do you know that you are God experiencing itself subjectively through a series of fragmented consciousnesses for the sake of entertainment? This life is a play. And it's time that we took center stage. If you are scared by anything in life, I'd advise you to find a way to deal with that fear, rather than run away from physical parameters. Avoiding surface parameters will, in the long run, prove irrelevant and fruitless when you realize that you are going to die anyway. Find that infinite part of you that gives strength, and let go of surface conflict.
Find some peace. However you do that. Panic will solve nothing.
