The context to this is saying about how they're not a fan of the subreddit LeftWingMaleAdvocates, which is a bad subreddit, it's mostly just anti-feminist and basically just MRA, but they just call themselves left-wing. Most of their "left-wing" stuff is actually just "classical liberal" talking points, so they are bad, but calling them tankie is ridiculous.
Every time I find a new group of reactionary opportunists calling themselves “Marxists” (don’t laugh!), I understand a little better why Lenin was so catty about their co-opting of radical terminology :back-to-me:
Lenin dunking on libs from beyond the grave and being an all around timeless shitposter will never not be funny to me.
