Admittedly this reading glosses over Stephen Universe being deliberately set-up to force Cartoon Network to acknowledge gay stuff. All the gems are allegedly nonbinary, but consistently she/her. Their relationships literally fuse people together. One of the central characters is the red/blue pair in the center... three seasons in. Rebecca Sugar, hot off Adventure Time's corporate case of the notgays, got to reveal that there's a been married lesbian couple onscreen since episode one.

Aaand Cartoon Network Europe still yanked their funding once that red/blue pair got an actual wedding.
