Calling the sky purple might be more
fun to some people than calling it
blue, but its certainly not setting anybody straight to tell them the sky is purple, or to try and make an
argument out of nonsense. Its also not really liberating to anybody to tell them the sky can be purple if they want it to be.
The country is still somewhat
free enough that you can call the sky purple instead of
blue without having your head examined (though not everybody has the luxury), though it doesn't really liberate anybody or
set anybody straight to keep bullshitting them by telling them to try and think the kind of abstract thoughts you want to see them think about.
