Reposting my old post from /leftyweebpol/
An interesting hentai doujin with leftist ideas is called A World That I Rule by an author called rozer.
(Spoilers for the basic plot)
Its about a bully who gets transported into an alternate reality where there are indigenous elves living harmoniously in a primitive communist tribal society. He eventually develops feelings for a girl, and later envy when he sees the girl fucking another elf (all they do is fuck each other). So he manipulates them through using food and introducing the concept of private ownership. He develops a class based society, appointing himself as king, then creating nobles who have special privileges, and slaves who break his laws for taking food for trees that isn't theirs. And he sometimes justifies what he does by telling the elves that without him, "society" would crumble despite the fact that he essentially crumbled their world and it turned to chaos. Eventually he left the island and got to another where he chose to simple integrate and not rule and in doing so didn't cause any destruction. It is quite similar in some aspects to Lord of the Flies.
The most ironic thing is that literally many of the comments to the doujin were like 'that world is so nice, but fuck the MC for fucking it up!'. Which is yet another display that most people support communist ideology as long as it isn't outright called communism/socialism.
In a way this 40 chapter webcomic is a demonstration that anarchism/stateless communism can't work when not in a bubble. Something to note in the original Communist theory is that the steps are usually a transition of capitalism to socialism and then to communism (which is stateless). However something many people seem to forget is the concept of global socialism. In other words, for communism to be achieved and not be disrupted as with these elves, the entire world needs to be FIRST SOCIALIST and then be edged into communism. In the webcomic the MC leaves to a new island and learns from his mistake… but we don't have another planet comparable to Earth to flee too, so humanity can't afford to burn it down, we need to know better.
