132: Are voluntary militias for the defense of a stateless society compatible with mass immigration?

The Mindcrime Liberty Show discusses whether mass immigration is compatible with the idea of a volunteer militia. The defence of a stateless society is a common point of criticism made against libertarians and anarchists. One of the solutions, other than rights protection agencies, proposed by theorists like Roderick T. Long and David Friedman is the adaptation of a much older form of organization: a voluntary militia. Can voluntary militias be compatible with mass immigration which many left libertarians such as Roderick T. Long support? Will the stateless society which is mass immigration friendly fight as a unified cohesive whole or will there be too many divisions, free riders and even fifth columnists?
