I don’t think that question has much meaning without context. There’s no such thing as a hard line ML. Ask specific questions and you’ll get specific answers.
Of course one can be an ML while opposing anything. But you have to oppose it as a process, not as an emotion. What do you specifically oppose? Why do you oppose it? What do you think gave rise to the phenomena to which you are referring? Where is your evidence for your claims? What would make you change your mind? Etc.
There are very few things that MLs just oppose because that’s “the line”. Marx, for all the complexity in his analysis, gives us a very simple framework:
- Human life requires human society
- Human society must remain for human life to remain
- Human society can be organized in such a way that it will end
- Human society can be organized in such a way that it will continue
- Determining how to continue human society is a process of theoretical analysis and empirical experimentation
Our job is to assert that we value human life, that we support it. Everything else comes from that. We do not need to support Stalin to be MLs, nor oppose him to be MLs. To be MLs we must engage in the analytical and empirical process of discovering how history has preceded us, how that has produced the present moment, and what we are to do now in our present context to bring about a future state that results in the continuation of human society and avoidance of the foreseeable collapses of that society.


Of course! We all should! Until we die. We should never stop learning and there is never an end to the things we can learn. Study more theory, but also study more history, and study literary critique and the history of literary critique, and study philosophical theory and history, and study political theory and history, and study economics and the history of economics as a field of study.
Study forever. Your positions will constantly be updating. Eventually you will have a bunch of good evidence for positions that you can rely on and build from, while always recognizing that new evidence could undermine those positions and you should be open to that.
Stop trying to establish what you support and what you oppose and start trying to identify what you are ignorant of and how you can fix that.
