I don't think it's right to pretend She-Ra was a more progressive show than it was. Episode 1 is Adora, who is a fascist goon but thinks she's a communist, learning that the monarchy isn't so bad because fascism is worse. That's... utter shite. Episode 1 Adora was more left wing in political views than any later version of the character. She believed in killing monarchs on sight, that's great, she should have stuck with that.
The show should have been about Adora creating a resistance movement with Bow and Swiftwind's help to dismantle the Horde AND the princess monarchy. She should have been recruiting Horde soldiers into an underground movement to fight for the ideals she was actually taught as a child. Instead, she abandons those ideals because a magic sword says she's a princess. If a magic sword said I was a princess, I'd destroy it! Fuck you, magic sword.
