Everyone is imperfect and unfit to rule. Place one person or another above everyone else and their prejudices define the movement. Put a hundred anarchists together and the personal failings matter little. When Proudhon started writing, women couldn't vote or own land. This is no-longer the case thanks in a very literal sense to the efforts of anarchists like Goldman and de Cleyre. It doesn't matter if Proudhon was a misogynist. I'm not Proudhon. You're not Proudhon. We're not Proudhonists, we're anarchists.
