Well, the main litmus test for the Communist Left is usually on the question of internationalism.
What do you see the role of national liberation movements as being? You say you generally agree with Lenin but don't give many details. Do you think he was right about the rights of nations to self-determination? What should be the position of revolutionaries today on war and national liberation struggles?
What about the Soviet Union and anti-fascist alliances? What was the correct line for revolutionaries to take in World War 2? Was it a genuine war between humanity and Nazi barbarism in which it was OK to ally with the democracies in order to defend the Soviet Union? Was it a war between different imperialist gangs, some with Nazi ideology, some with democratic ideology, and some with Marxist-Leninist ideology, but all committed to defending different national capitals?
Elaborating a bit on these questions might get some positions into the open so we can discuss them.
