Zizek's take on anarchism is so bad. "I don't want to have to debate for days about what kind of water treatment plant to build."
No shit, dude; few people do. But guess what? Few people are even qualified to have that conversation and I'm pretty sure the collective will happily delegate that task to people who actually know what they're talking about.
Participatory democracy doesn't mean spending every waking hour debating and voting on the daily minutia of running a society.
