so... do marxists that aren't marxists leninists do not agree with lenin? or do not see his methods as something that should be repeated or taken into account?

"Marxist" is a vague term deployed by people who don't want to tell you their explicit ideology because it inevitably alienates some group of people, or because they don't know what their explicit ideology is yet.

I'm trade unionist sometimes. I'm a marxist at others. I'm an ML at others. I'm even a socdem when I was still doing work in the labour party (or else I'd have been purged).

In some situations I might say socialist instead of communist because it's just more useful to use that term.
