^ Ideological "moderation" results in a slide toward the same centralized and exploitable control that you presumably find objectionable about communism.
Moderation as a political compass isn't that much better than full totalitarianism. Moderates want certain values and actions forced upon others all the same. The result is a tendency toward more and more government control in each election cycle, with no regard for the principle of limited government. The Republican's ideology justifies the bad foreign policy, repressive social controls, Big Brother, et. al. The Democrat's ideology justifies various immoral and ineffective economic policies. It's better to not have decisions made and values enforced by a group of elected elites in the first place.
I think the verbiage we use to discuss political compasses and degrees of ideology has been distorted. Any policy of government action, being coercive and an initiation of force, is what is actually extremist. The status of freedom/control on most single issues is dualistic. Either you have freedom on that issue or you don't. For some reason somebody is allowed to advocate all kinds of social control, theft, and aggression for certain issues and still be called moderate just because they want freedom in other issues.
