I say this because one of their main theorists George Fontenis had his organization called Federation Anarcho Communiste run for parliamentary elections. Also they emphasize "theorectical unity, tactical unity". And also because they are against individualism which anarcho-communists like Malatesta and Kropotkin say are a part of anarchism. And also because as their Dielo Truda Platform says "In the social domain all human history represents an uninterrupted chain of struggles waged by the working masses for their rights, liberty, and a better life — In the history of human society this class struggle has always been the primary factor which determined the form and structure of these societies" and so they have a marxist view of history.
