So a few ideas clump together into one ideological fixation. The actions of the government right now are laying the groundwork to repress the coming Revolution; the people must be warned; and present actions, which may be reasonable, must be opposed to preserve the future feasibility of the great revolt.
For the Right, the gun registration and background checks, no matter how reasonable they are today must be opposed because they will, on that great getting up day in the future, be used by the government to confiscate the arms of the freedom fighters.
For the Left, finding out the communication links between foreign militants and people in the United States must be opposed because that spying will be used to defeat the revolution in the future.
Essential to this is the wildest exaggeration of government capability and practice. How often do you hear that the government is on the verge of confiscating everyone's weapons? How often in the last few days have you heard that the government is actually listening to everyone's phone calls? The drone killing of an American citizen who had relocated to Yemen and was actively involved in Al Qaeda there turns into a government that plans to execute citizens on US soil for political reasons, perhaps for filing an improper application for a tax-exemption.
As a result, what the government does is not measured against the concrete problems they are trying to solve. They are measured instead against a dark future fantasy: if the government was completely totalitarian and the people were in revolt, how would these limited exercises of governmental power be possibly stretched into something fatal to a free people? It's always 1935 in Germany.
Against that grim fantasy, nothing is reasonable, prudent, measured and effective.
So hysteria reigns, making governance impossible.
As we now see.
