Graeber is an anarchist. In the past, he has also participated in Black Blocs, a confrontational protest strategy used at the World Trade Organization meetings in Seattle that the Canadian Security Intelligence Service has ominously warned might lead to violence at the Quebec summit. We're trying to create alternative institutions that would make the state unnecessary. Graeber's casual, friendly tone tends to gloss over some of the more contentious aspects of his world view, but he articulates anarchism as a political philosophy like any other, rather than some sort of scary anti-social behaviour. But a lot of anarchist rhetoric found on the Internet and in newsgroups is confrontational and sometimes downright inflammatory.

The RCMP are certainly worried. Anarchists, with their philosophy that justifies the destruction of private property, will draw disenfranchised youth to participate. The use of petrol bombs and similar disruptive instruments by a few radicals cannot be ruled out. Black Blocs are not formal groups but informal groupings of individuals who come together at demonstrations, usually with an agreed-upon set of tactics. They operate secretively and are organized horizontally into affinity groups, which co-operate and make decisions about action by consensus both before or during demonstrations.
