If they do not, if they accept the murder of the truth, then it is only a matter of time until they, like Stack, accept the murder of the revolution and the workers fighting for it. The real differences between anarchism and Leninism can be seen from the discussion on Kronstadt. They, like anarchists, rejected the idea that soviet power equalled party power. For anarchists, a revolution will solve social problems in the interests of the working class only if working class people solve them themselves. Similar events occurred all across Russia at the same time.
History provides the answer with the rise of Stalin.
By its very nature a dictatorship destroys the creative capacities of a people. The Kronstadt sailors and workers were not utopian enough to think that reconstruction would occur instantly. Stack's justification for the suppression of the Kronstadt revolt simply means that for the SWP, when necessary, the party will paternalistically repress the workers for their own good. Ultimately, Stack's comments show that the SWP's commitment to workers' power and democracy is non-existent. Needless to say, space excludes me from replying to the rest of the article.
