I also wanna second junedave, and was thinking of saying this in my first post but didn't want it to be like, egregiously long. But yeah, while exploring a postgender society would be really cool, I don't think that's what's going on with Earth C. Sure, some characters give implications of that, but our main cast are not the most integrated into Earth C society, and it honestly seems moreso like wishful thinking on their part. Given that Earth C is basically poorly copying Old Earth America as a blueprint, it seems likely infact that there is gender inequality. I'd argue you can see this with Roxy in the Epilogues. He does explore his gender and transition when with Callie and living in the Carapacian Kingdom, but when in Candy, when the narrative sort of shifts to put her in a relationship with John that isn't good for either of them, obviously she doesn't put those feelings away, like she said, but there does seem to be a societal pressure on her in that timeline that is lacking in the other. Overall, I imagine that Eartch C is closer to a postgender society in the Carapacian and Consort Kingdoms than in the Human and Troll Kingdoms, which might itself still be a really interesting thing to explore!

But, also, John grew up on regular old Earth. And even if Earth C was a postgender society, we know that John is the person who has least integrated themself into Earth C society. So, I still think June is going to have to deal with a lot of societal pressure and internalized structures.
