That's amusingly written and I agree with it, but how is the second father, the non-authoritarian one, being postmodern, exactly? Zizek is the postmodernist here—he's the one offering a postmodern analysis. More precisely, this is pure Foucault: power that forces physical compliance is lesser, while power that reforms your own relationship to yourself is more insidious. Zizek just describes it with a more earthy example than Foucault ever would. Real postmodernists don't do earthy.
