>>109323084Korrasami is pretty bad representation at least from a writing standpoint. It comes pretty much out of nowhere between two characters that didn't even interact much at all. Then add on the god awful stuff in the comics that forced in lore about Kiyoshi being bi and Sozin hating gays for some fucking reason.
Good representation is probably She-Ra. Nobody makes a big deal about it and it's existence doesn't really compromise the story.
