The phenomenon of political parasitism, which to a large extent is also the result of the penetration of alien ideologies into the working class, has not been accorded, within the history of the workers’ movement, the same amount of attention as other phenomena such as opportunism. This has been the case because parasitism has only significantly affected proletarian organisations in very specific moments in history. Opportunism, for example, constitutes a constant menace for proletarian organisations and it expresses itself above all when the latter are going through their greatest phases of development. By contrast, parasitism does not basically manifest itself at the time of the most important movements of the class. On the contrary, it is in a period of immaturity of the movement when the organisations of the class still have a weak impact and not very strong traditions that parasitism finds its most fertile soil. This is linked to the very nature of parasitism, which, to be effective, has to relate to elements looking for class positions but who find it hard to distinguish real revolutionary organisations from currents whose only reason for existing is to live at the expense of the former, to sabotage their activities, indeed to destroy them. At the same time, the phenomenon of parasitism, again by its nature, does not appear at the very beginning of the development of the organisations of the class but when they have already been constituted and have proved that they really defend proletarian interests. These are indeed the elements which we find in the first historic manifestation of political parasitism, the Alliance of Socialist Democracy, which sought to sabotage the combat of the IWA and to destroy it.
