You seem to be asserting that people in general care less about politics than they should. I would challenge that assertion; it seems unlikely on the face of it.

As noted in OP, we had much more impact on politics (and its close neighbor, tribal signalling) in the ancestral environment than we do now, and it was much more directly a matter of life-and-death. Thus, we are hard-wired to care about politics to a greater extent than we should.

You're new here, and so you're not used to our community norms - in those cases, we try to cut people some slack. But it really seems to me that you're not ready to be making contributions; try to restrict yourself to asking questions that might further your understanding of rationality. You appear to be incapable of seeing that your enemies are not evil aliens - you describe communists as 'idiots', as though there is no way an intelligent, well-meaning person could believe that communism is a good system of governance*. I shall refer you to this chestnut from G.K.Chesterton:

In the matter of reforming things, as distinct from deforming them, there is one plain and simple principle; a principle which will probably be called a paradox. There exists in such a case a certain institution or law; let us say, for the sake of simplicity, a fence or gate erected across a road. The more modern type of reformer goes gaily up to it and says, "I don't see the use of this; let us clear it away." To which the more intelligent type of reformer will do well to answer: "If you don't see the use of it, I certainly won't let you clear it away. Go away and think. Then, when you can come back and tell me that you do see the use of it, I may allow you to destroy it."

So it is with opposing viewpoints. Policy debates should not appear one-sided. If you do not understand how an intelligent, well-meaning person can have a position, and it's a position that lots of people actually hold, then you do not understand the position yet.

If you really want to post about politics rather than rationality, there are plenty of forums for that - many more than there are for rationality. If you do continue to post here, I would be very grateful if you made your comments short, to-the-point, and on-topic.

*As a minor footnote, note that what you were really commenting on is people's responses to one question on an informal survey, which many people criticized for not doing a great job of carving up the space of political ideology.
