That voters are ignorant comes as no surprise to anyone who isn't themselves ignorant.
Hypothesis: most discourse is broken, not just layhuman discourse. I expect any working discourses to work by accident, not by design.
Test: let's have a discussion about utopianism and revolution. My general impression is that anti-utopianism is opposition to legitimately broken political philosophy by way of strawmen. It supposes that utopian philosophers suggest a flawless, suffering-less society is possible, and in the process tend to be not anti-Progressive, but anti-progress. (Agree that proggies are probably utopian...we'll see, as below.)
Can I get a summary of how I might recognize a utopian system, and why I can be sure that these features predict that the political philosophy is self-defeating?
