Is political correctness a solution — or a desperate cover-up?

Philosopher and cultural critic Slavoj Žižek has a bone to pick with the PC movement. While he doesn’t buy into the right-wing paranoid view that the politically correct among us are "evil people who want to destroy the American way of life," he does think they’re doing some damage. 

Žižek questions whether censoring our expression really addresses racial tension – or does it merely give birth to a politer form of racism (or sexism, or religious and political differences)? Tolerance has started to work against its own agenda, becoming a patronizing insult to those who think differently to you, a way of brushing off and compartmentalizing differences rather than listening and connecting.
