Loyal factionalism vs. Anti-factionalist opportunism   –>  Loyal factionalism, because the unity formed by anti-factionalist opportunism is illusory, based on silence, not democratic discussion and democratic centralism.  The center of the party, which is the theoritical advancement of Marxism,  under anti-factionalist opportunism could in fact lay outside the party, excluding the possibility of a revolution until after loyal factionalism is re-introduced.
