If you're looking for the anti-revisionist Marxist Leninist party line I suppose Espresso Stalinist's page would be a start

Some highlights:
1) Marxist-Leninists, unlike Trotskyites, do not attempt to “jump over” the various stages of revolution. Marxist-Leninists, unlike Trotskyites, believe that necessary objective conditions must be present before advancing to the socialist revolution. Leon Trotsky advocated “jumping over” the bourgeois-democratic revolution in Russia and proposed leaping immediately to the proletarian revolution. History confirms that Trotsky’s line would have condemned the proletariat to isolation in Russia’s bourgeois-democratic revolution and set back the struggle for socialism.
2) Marxist-Leninists, unlike Trotskyites, join, support, and build the general democratic movements. Marxist-Leninists, unlike Trotskyites, believe that the struggle for democratic rights under capitalism is important for the working class.
3) Marxist-Leninists, unlike Trotskyites, believe in the correctness and ability of the working class to have allies to rally and lead in the revolutionary struggle. Leon Trotsky also advocated rejecting the peasantry as a potential revolutionary ally of the working class.
4) Marxist-Leninists, unlike Trotskyites, are not orientated on “revolutionary wars which export revolution” that do not take into account the objective class relations within a given country. Marxist-Leninists understand that revolutions mature when the class contradictions within a given country are heightened to the point of national crisis and do not believe that revolution can be spread “by red bayonets” from the socialist countries. It must be pointed out that Leon Trotsky advocated provocations which would have proved disastrous to the Soviet Union. Lenin showed that “[Trotsky’s] ringing phrases about ‘revolutionary war’ served as a screen for petty-bourgeois adventurers, who objectively were helping the enemies of the revolution. Addressing the supporters of ‘revolutionary war’, he announced: ‘…In your objective role, you are a tool of imperialist provocation. And your subjective ‘mentality’ is that of a frenzied petty bourgeois.’” (Lenin, CW #27 330).
5) Marxist-Leninists, unlike Trotskyites, believe that socialism can be built and consolidated in one country. Marxist-Leninists, and not Trotskyites, supported and defended the former socialist Soviet Union. Leon Trotsky and the Trotskyites went to the lengths of asserting that the practice of building socialism in the former Soviet Union would serve the interests of the international bourgeoisie and not the working class.
6) Marxist-Leninists, unlike Trotskyites, do not swim in the sewer of crude anti-Sovietism and absolute condemnation of the former socialist Soviet Union from 1917-1956. It must be stressed that the history of Trotskyism has been the history of the petty-bourgeois Trotskyite slandering of the former socialist Soviet Union. Throughout the history of socialism, when the anti-communists sought to build up their arguments against socialism, they took to the Trotskyite statements as “undeniable proof” about the “problems” of building socialism. When they wanted to drive a knife into the Communist Party of the Soviet Union and other Communist Parties, they looked to the Trotskyites, who claim the cause of international revolutionary struggle was “betrayed” by the Soviet Union. The anti-communists come in many shades, but their useful puppets are Trotskyites.
