For the past three weeks or so, people have been meeting at The Flying Squirrel Community Space (285 Clarissa St., formerly the Flower City Elks Lodge) to discuss anarchism. Having not attended the earlier meetings, I can't really tell what constitutes anarchism (e.g. self-rule? using the self-organizing facet of humanity? not having a government?) but I couldn't help but attend the seemingly unusual topic of "Anarchism Against Racism, Sexism, and Homophobia".
I'd say there were about 15 people there, and most of them had attended the other meetings and read the associated articles — it's something of a free-school model. I think everyone expected a more lively discussion because the topics were so emotionally-charged, but the ground we covered between was fruitful and interesting.
In short, Capitalism depends on exploiting value to gain more than is spent. Through that, it seems to demand an underclass: a group of people who are considered lesser and therefore are free to be exploited. (In fact, the only way great wealth and power is achieved is by exploiting others.) And the way to identify the underclass is to tie the "underclass-ness" to a defining characteristic: woman, gay, black, Irish.
Anarchism, by eliminating the presumption of authority, denies the creation of an underclass. In other words, anarchism (when considered "self-defined rule") does not permit the creation of people having authority: it is up to each individual to grant that authority. So there is no way for an authority to declare that you are X and therefore shall be exploited; rather, you as an individual would have to grant an authority that power, and permit yourself to be exploited. Presumably you would never volunteer for that.
The trouble is that the system I live with (that is, in America) will always find a new underclass to exploit. Lately it seems Hispanic people and followers of Islam are the newest targets (not that they were ever considered equals). Although we have also exploited the Chinese in their own land to that end, and I suspect the next source of cheap labor will be on the African continent. I find it a distasteful cycle that I'd like to see end sooner than later.
