The best part of Žižek's Violence is his brilliant analysis of the concept of tolerance. He shows us the scary possibilities implied in the blind worship of unconditional and unthinking tolerance:
"What lurks at the horizon. . . is the nightmarish prospect of a society regulated by a perverse pact between religious fundamentalists and the politically correct preachers of tolerance and respect for the other's beliefs: a society immobilised by the concern for not hurting the other, no matter how cruel and superstitious this other is."
The reason why we "tolerate" seeing Muslim men who lead women behind them on a piece of string, as if these women were dogs, is not respect for a different cultural tradition. The only truth behind this "tolerance" is contempt, lack of respect, and the desire to infantilize the menacing Other. How would you react if you saw a Western couple interact in this way? Would you sneer? Give them a piece of your mind? I know I would. But when somebody we can easily identify as the Other does things that offend our sensibilities, we are supposed to avert our gaze in an utterly hypocritical show of our worldiness and sophistication.
Otherness is always scary. Tolerance allows us to deal with our fear by treating the Other as a wayward child who is allowed all kinds of pranks we will never put up with if they came from an adult.
