The people of the American Police State will never have any hope of fighting government tyranny if we're busy fighting each other.
When all is said and done, the only thing we really need to agree on is that we are all Americans.
So if this isn't your fight--if you believe that authority is more important than liberty--if you don't agree with a particular group's position on an issue and by your silence tacitly support the treatment meted out to them--if you think you're a better citizen or a more patriotic American--if you want to play it safe--and if don't want to risk getting shot, tased, pepper-sprayed, struck with a baton, thrown to the ground, arrested and/or labeled an extremist--then by all means, remain silent. Stand down. Cower in the face of the police. Turn your eyes away from injustice. Find any excuse to suggest that the so-called victims of the police state deserved what they got.
But remember, when that rifle (or taser, or water cannon, or bully stick) finally gets pointed in your direction--and it will--when there's no one left to stand up for you or speak up for you, remember that you were warned.
