Lucky White Girl maps a conversation rolling through the blogosphere regarding the intersection of privilege and blogging. It's really interesting stuff.
The debate started with a Feministe discussion on whether feminist sites should allow non-feminists to post comments. I haven't been specifically following the thread of the conversation, but I have intersected with it in two places. First, back when Alas, a Blog was considering having threads reserved for "Radical Feminist Women" only, I wrote a post objecting and proposing instead that certain threads be "reserved" for anti-feminists to prevent sidetracking. AAB ended up taking a roughly equivilant stance, leaving most threads open while reserved some for "feminist or feminist-friendly posters," which, while limiting, is nowhere near as constricting as "radical feminist women."
I also read Dark Daughta's post on male feminist bloggers occupying a privileged position in the feminist blogosphere. This post I think was targetted directly at male-operated AAB. I read the post at about the same time as I was writing my "Privileged Man's Guide to Life" post, which I think parallels this discussion nicely as well.
In any event, it's an interesting discussion, and a topic that should be explored in depth (albeit civilly--a right to be hostile, even if justified, doesn't make it the best theory or the best practice).
