We've already had plenty of dystopias: Nazi Germany, the Soviet Union, Maoist China, Cambodia under the Khmer Rouge, North Korea today... As for a utopia? Nobody can agree on what that would look like. When somebody claims to have a plan for a utopia, my first question is: "for whom?"

How does any ideological utopia work without excluding anyone? I have yet to see a satisfactory answer. The paradox of tolerance would suggest that utopias are impossible, at least with human beings.
