The moral outrage inherent in the Oppressor-Victim narrative that drives Liberalism justifies all sorts of totalitarian control. Liberalism has no internal critical brake. College campuses are examples of these mini-states where the paranoid or vengeful feelings of the Officially Protected Sacred Victim Classes are used in order to stifle and criminalize opposition. In Bill Whittle's words, they become liberal madrassas, uttterly deaf to irony or argument, like the British "Equalities Minister" who said that in order to achieve equality we must treat people unequally. Trevor Blake's list of First Amendment crimes is dominated by liberals, not by "the religious Right." It makes for grim reading.
Ex Cathedra thinks that, eventually, if Liberalism is not completely triumphant, it will provoke a response from the Right that will have to be at least as rigidly controlling if it is to succeed. They'll call it fascist but it will simply be a survival-driven traditionalist version of their own totalitarian urge, brought on by their own excesses.
PS This stuff reminds me of the actual Liberals I have known through work, etc. They would find the word "liberal" an insult since they were self-consciously farther to the Left. My recollection is that the worst of them, the most coldly and impersonally ideological were the women. Madam Mao was no accident.
