 While GMAC argued that this adaptation was necessary in order to increase mobility (the life blood of a minimally equipped street fighting force), other aspects of the anarchist community criticized these prescriptions as authoritarian in nature and therefore contradictory to the principles of anarchism.GMAC countered that their proposals were in line with those witnessed during the Spanish Civil War via the CNT and FAI.Of those groups that supported the basic tenets of GMAC's views were the Barricada Collective (Boston-MA), and Columbus Anti-Racist Action (Ohio).
