Yes, we're comrades who share a common struggle. But do you mean anarchists and marxists? Cause every single anarchist I know in real life is also a communist. And ever anarchist movement or org or squatting place or whatever too. Only online do I ever find anarchists who distance themselves from the idea of a stateless classless society (the universally accepted definition of communism). Like I assume you're okay with society being stateless. So you want it to have classes? Not really, right? Marxists and anarchists have different strategies for how to get there, but clearly every anarchists who wants a classless stateless society (i.e. communism) is also a communist.
