Are there any anime where any revolutionary thought isn't discarded by the end?

Red Sails: The Swerve

Anti-Communism is deeply embedded in the publishing industry in Japan

That being said, some revolutionary optimism sneaks by, I've heard One Piece is good.

Maybe manga, but anime is expensive to produce and investors need to green-light it. Thus the closest thing to revolutionary ideas being proven right can't make the investors look like the bad guy that can be defeated.

It would be nice if China did though. I'd love to see a fantasy setting undergo a socialist revolution. Utilizing the magic of the world to advance the forces of production for factories and threw the craftsman mages under the bus to produce magical items in magical factories. The experience alienation. Land use policies change to farm magical animals like unicorns for their magical ingredients in factory farms. Clerics and Paladins that serve gods of wealth drive out all of the indigenous druids and shamans to extract from the land without giving back. Even in death, the workers are not freed from the capitalist system. The exploitation of the workers makes it difficult to pay for things, so when a loved one dies, their body is sold to a necromancer to do eternal mindless labor in the factories to assemble non magical items or till the fields.

The spiritual death of the world offends the goddess of the planet and she strikes back with plagues and storms to undermine the human supremacist, unsustainable ways of capitalism. But the ingenuity of creating magic and technologies can hold the world goddess's power at bay. Thus she has cast out the ability for magic to work in this planet in many ways. Arcane magic still works, but magic of the gods can't enter her realm. However some people can cast divine magic spells, but it is only because they work in her favor. She no longer tolerates the gods that even the artificers admit are destroying the world. Those most exploited by capitalism sometimes gain a blessing of the godess, but they must hide this from authorities. It is up to the workers exploited by the system to use their power, whether blessed by the goddess or not to change the world as it is to one that serves the all sentient races and in harmony with nature.

Afaik none, even if there is more or less revolutionary idea or character presented as positive, at some point class collaboration is always presented as the only possibly good outcome. So, more or less like entirety of capitalist media.

Code Geass never discarded its anticolonialist theming

Isn't One Piece revolutionary? I didn't watch it since you know, number of episodes, but I heard that it is. And which is the one about terrorists?

I haven't finished it, but probably the Karl Marx one(though it is a donghua, not an anime)

No.6 comes to mind though I recommend reading either the novel or the manga before even glancing at the anime. The author is part of the Japanese Communist Party and though I have some gripes with how the story ended I still think its worth a read. Also yaoi happens

One Piece : I gotta post some spoilers to talk about it:::: large plot spoilers The main characters dad is literally based off Che Guevara and is always portrayed as the side of good. His ship is named Granma, same as Che's. He's the leader of a force named the revolutionary army. His second in command is named Invankov: queen of the kamabakka kingdom which is an island of gender fluid people who can physically change genders any time they want thanks to Invankovs hormone powers. They go around liberating islands from the world government and freeing slaves.

The main character and his crew embodies freedom and I'd say communist ideals but they never really explicitly say so.

There is an arc where they must dispose of a king who was hoarding doctors for himself. It feels like a metaphor for socializing healthcare.

In most of the arcs after the introductory ones, they team up with natives to force out occupiers who are displacing them, or straight up enslaving them.

One of the first long form arcs they fight what's basically a world government funded NGO who is trying to coup a king in the Middle East by controlling the resources (water).

They fight the CIA of their world.

There are consistent themes of freeing slaves throughout.

The world government is controlled by disconnected incestuous billionaires that all gave themselves the title of "saint"

There is a villain who is liberal coded, who creates a Disneyfied kingdom using fear.

Another is libertarian coded who occupied a land that he turned into a weapons manufacturing island.

There is an alt right coded villain who also turns the occupied kingdom into a weapons manufacturing island. ::: It's a big commitment due to length.

I love the absurd art style (aside from every woman looking like the same character and some portrayals I found insensitive or offensive) but a ton of people have a hard time getting past how goofy it looks. Characters can look ridiculous and proportions mean nothing. Humans heights seem to vary between 1ft - 30ft tall.

The absurdist and cartoony nature of it can be off-putting to a lot of people but personally I love it and wish more things were like it.

There are a lot of problematic elements throughout that you'd need to look past and just enjoy the overarching message.

Iron blooded orphans is good
