It's pretty clear to me that it's attempting to destroy the misconception that some newer leftists have about Socialism and Communism, who have just learned about it and think it sounds great, but haven't actually dug into the structures and realised that while a lot of it is indeed great, it also takes a lot of work still.

Would it be tankie to bash whoever thinks reading tarot is labor, peacefully? Absolutely, but I think it's more tongue-in-cheek, and I actually think the original person the joke is replying to is also being tongue-in-cheek, to an extent.

At least, that's my non-tankie interpretation. Dirty jobs would absolutely exist, and while it would be likely that this work would be split amongst the broader workforce, the idea that people can get by without actually contributing what they legitimately can is Utopianism.

Did I read too far into this, for what very well could be a tankie being an absolute piece of shit for no reason? Yes, but I hope I'm right and both are decent people making sarcastic fun.
