A pair of wolfs (drkitten & paximperium) will have an easy picking of a disorganized herd of lemmings (lightfire22000 & friends).Provide a fight that you wouldn't want because you'd get killed. Anybody who tried to own slaves would get killed. Once they all got killed, no one would enslave others. Once you coerce and seize property, you become government and should be abolished anyways.
Highly organized fighting forces are far more effective then 'militia'.
