counterargument
he show is about how a single straight white boy managed to solve all the problems a bunch of colored women could not solve for millennia

*human / monogendered polymorphic space rock
I mean yeah, what protagonist isn't part alien/demon/whatever nowadays?
*an overly sensitive teenage boy who "naturally" has puberty suppression, and likes to cross-dress.
That puberty thing was more about him not wanting to grow up, and even if it was an anology about hormone suppresion, then wouldn't he still grow up but looking more like a girl? As for the cross dressing part, I only recall him doing that once, and it was to make Sadie feel better about herself. He did seem to enjoy it but you make it sound as if it's a regular occurring thing.
*upset that his fellow diamonds, aka family, refuse to understand Pink's reinvention, or use Steven's preferred Pronoun (this is the entire final story).
Pink didn't want to destroy planets and civilizations anymore, since when was common decensy some leftist propoganda shit,
and if you were some kid constantly being mistaken for your mom, would you really be cool with that instead of people treating you as what you really are?
*fat & uneducated (I couldn't resist the low blow).
Well the uneducated part is true, (though I'm not sure why that's inherently bad from a character stand point) however this whole "Steven is fat" joke is just bullshit. He was overweight at the start of the series but now looks like an average sized kid. Wouldn't really go as far as to call him skinny but it looks to me like he took that work out thing seriously.
