I don't consider myself a Marxist, Leninist, or communist of any stripe and haven't had a problem so far. I'm far enough left that I refuse to call myself a liberal, but I suspect the folks who consider themselves Marxists probably think I'm too far right to self-identify as a leftist. (Although I do.)
Shitload of downvotes a time or two, but that's about it. I just wanted to be on a Lemmy instance that was honoring the fedipact, and preferred it to have an instance ethos to the left of mine rather than to the right of it.
