My thought with Jasper was not "black." Amethyst i could see being coded that way, but Jasper's meant to be an homage to Jem And The Holograms, or in a broader sense, that 80s style of Glam Rock hair and face paint. Her racial coding is subordinate to that. She's a glam rocker, or possibly Punk, given her attitude (and that the two styles overlapped somewhat for women).
I have no idea why you're so upset. I explained that the majority of fanart in which Jasper is a human depicts her as a black woman with vitiligo, and you immediately jumped to the fandom being irrational and crazy because the show hasn't said that's true.
Fandom exists to create and transform a work, through art and writing. I don't understand your problem with that.
Though Mystery Girl having her own crew of doppelgängers would be hilarious.

This is kind of my point about a show being overanalyzed more than The Wire. Aren't most of the episodes essentially him defaulting to the knowledge of the Gems in serious situations?
And Mystery Girl has just gotten over her crush on the Pearl expy.
The Crystal Caverns A bird's gotta sing.

They aren't perfect...
If it wasn't for that one thing that happened, they'd not show those kind of emotions.
