This country runs on money, these politicians run on money, money is the lifeblood of modern america. Wanna know what brings them money? Information. Reach the point where you can get your information through redundant sources, you're a little safer, keep backups of your files, have your own sources of power(illegal in many cities I might add), and have your own sources of food. If you can provide these things for yourself, then you can attack the system with near impunity from your own actions, and the suprising thing is, you'd probably end up in the poverty tax bracket, and qualify for handouts, which you could turn against them. In modern American, patriots don't need to attack people, people are too numerous, and too insignificant to modern life (part of our current problem). Infrastructure is the key. Once you attack the infrastructure, you place people in a situation some of them have never been in before, a situation where they can't rely on big brother to provide for them, to supply them power, to magically make food available, and some of them might start thinking about how dependant they are on the system, and without killing anyone(pissing them off pretty badly though), you'd have put people on the road to a little greater awareness.
If the time ever comes to rebel, just remember that perk of modern life, that for the most part you can upset life to the extreme without killing a single person. I'm certainly not saying don't be ready to, or don't train how to, but just keep options in mind.
Whatever you do though, don't attack the structure of the internet. When people get discontent, or disillusioned with the system, they will need a place to vent, and when they come vent online, there will be plenty of others to vent too, which might increase thinking even more.
