The American Declaration has its weak spots, but as a liberal document it works well. Let’s face it, Zizek looks so unahappy he is downright creepy. Perhaps he would have the reactionary sufis invent suffering for the masses. That would do the trick. And the sufis are waiting, witness Gurdjieff using occult methods to create psychological diseases, much suffering, sabotaging health, much suffering, slow motion crucifiction. The sufis are licking their chops, a suffering slave is a useful drone.
Zizek doesn’t speak for the left.
