While I do identify more with Marxist Leninists than any other tendency, I don't like these labels a lot. I think sometimes this leads more to group identity, so people are forced to uphold values of a particular tendency rather than criticize and evolve our thinking.
Marx and Engels laid the foundation of the system and there were many contributors to our field. We have people like Rosa Luxemburg, Kautsky (before he turned into a renegade), Bebel, Liebknecht, Plekhanov, Bukharin, Lenin, Mao, Trotsky, Stalin, Losurdo, Deng, and many others. Some people held contradictory views, some argued against each other, but I do think debating is important to make our field grow scientifically. Our science needs criticism and contradiction in order to develop itself more and to respond to our current practical issues.
It does not mean, however, we should embrace eclecticism, as some people may criticize correctly. When we are building a political movements we need to have a clear political line and avoid embracing everything, or we end up with nothing. In this way, MLs were the people who brought me to Marxism, and I tend to agree with them more than anyone else.
