I get amused when I read about Democrats or Republicans trying to win the favor of the libertarian voters. It would be easy to do: reject force as a political tool and liberty lovers will be on your side. Of course, it would be the Tyrannocrat who did the "joining" in that case, but that is as it should be.
Why should anarchists or libertarians "join with" any other political group? WE are the ones they should be clamoring to join. We are the only group with a real difference. The Tyrannocrats can argue like spoiled toddlers over who is better to control "the people" while we quietly take that control out of their hands and place it on a high shelf out of reach.
You don't get clean water by mixing in sewage. You get clean water by filtering and treating the sewage until all that is left is the clean water. This is all we are asking Democrats and Republicans to do. Filter out the large rotting chunks of the police-state first. Filter out your control-sewage and embrace the clean, refreshing water of liberty. Any filtering or treatment at all will at least move you in the right direction. I have tasted the sludge of the state. It does not slake the thirst.
