What a profoundly unhelpful comment. "Wait 100 years for something to happen" is not strategy on any level, even if you think our solutions are extra-electoral.

eta: To be a bit less harsh: If you think there's no hope building meaningful political power in this generation, then the question is rather: how do we build the communities that can survive on the margins and be ready when the time is right? Basically, I'm not letting you off the hook, no matter what. :p
