Claire Wolfe, in her book 101 Things to Do 'Til the Revolution, made the statement "America is at that awkward stage. It's too late to work within the system, but too early to shoot the bastards."
The question constantly arises, "Is it time, yet?" Yes, it is time. It has been time since the dawn of humanity. Look back at history and you will see there has never been a time that fighting against oppressive rulers was the wrong thing to do. If our species had always remembered that fact, and exercised it, we would not be in the situation we are in now.
Our problem is that we abdicated our responsibility when it was easy to fulfil. We thought that the tyrants were not too bad; besides we knew them personally. Now the rulers have erected a huge wall of "laws" designed to ensure their "continuity of government". People with a blind sense of "lawfulness" will point to those laws and say that it is wrong to fight back against the evil rulers. Only if you look at it through the eyes of the tyrants themselves is it "wrong". Of course they will forbid fighting back. Tyrants always do.
Before anyone gets worked up, I'm not advocating any actions here, I just want you to realize that regardless of whatever "laws" the tyrants erect around themselves, fighting against tyranny, with whatever you have, is never wrong.
