What part is contradictory?
Most of america is "against the terrorists" and so preoccupied with what they are spoon fed by the media to realize the dick in their ass. The other larger percentage is aggravated, but nowhere near considering a revolution. The rest are "crazy militant extremists", b/c anyone who DOES try anything are quickly labeled as such by the media and government, and quickly dismissed to their cages in a prison. And what they usually do is pretty dumb and/or poorly planned. They are usually from a racist group (mostly the white supremacists, and/or their affiliates), and they usually direct their attack at other races. Which accomplishes nothing on a large scale, and gets them quickly labeled as the morons they are.
We would need large numbers, great, honest leadership, and a well thought out game plan to stand a remote chance of a complete overthrow. Which is EXACTLY what needs to happen. I can't fathom this country lasting another 100 years the way it is going, or even with any minor passive change.
