>>2755256Classic Vanilla anarcho-syndicalist theory trusted the syndicalist Form to inherently lead to revolution and in some cases they had advocated for a more mutualist-type social form where there would still exist a market to a certain extent with small firms and artisans in "comradely" competition, and still nations and a global market but with the ideal of solidarity in mind, etc.
Anarcho-communist theorists (i.e. "Platformism", "Especifismo") argue that syndicalist structures alone are not enough as they could capitulate to reformist/opportunist tendencies by nature of serving as a union in the context of capital, and it insists on the importance of a parallel political organization (a "not a party" of the more or less Democratic Centralist variety but horizontally organized) to take the lead and ensure a libertarian communist trajectory in the anarcho-syndicalist unions and to work towards building hegemony in the proletarian cultural sphere.
It should be noted that these are broad generalizations and there exist major differences in perspective and praxis between groups, national orgs, and individual militants from the beginning till now. Just look at the IWA vs ICL debacle or the many schisms in the CNT over the years.
