Regardless of what you think of communism, (I'm not a fan myself), I very much doubt that they're really communists. I'm sure they'd like to rise from their couches (huffing and puffing, complaining about their knees) against the thin oppressors and have free junkfood all day everyday, but there's really nothing more to it. With how low-effort their entire lifestyle is, I doubt that they ever read Marx, know one bit about communist history, know any branches of communism or the important historical communist ideologues...  To them it's just ''free unlimited junkfood, thin people in camps, free money, and unlimited asspats''.
