I quoted the maker of the show, and based on their own words, this show in particular was more than just having a character.
Steele describes this as not just being simple representation, describing it as “meant to be in the structure and the bones of the show.”
And in another part of the interview:
TD: The original was supposed to be more of an adult cartoon, and I know it still has a curse word and references to porn in it. And I know that you were asked to take some of that out to make it more youth friendly. So I guess my question is: what was that decision like when you were making the Netflix show? Did you always want it to be more friendly for kids? Or were you originally thinking about making it adult-oriented like your original project?
HS: No, funnily enough the adult comedy was added to it. I didn’t pitch it as adult, and then Cartoon Hangover’s brand at the time was trying to make more adult cartoons, and then halfway through production they changed their mind because I think it demonetized their videos, and that was their whole business model. So it used to be a lot worse. There was some proper bad stuff in there.
So we took out what we could and we left in the stuff we did, and we still think it’s funny. And then the comic was more YA, I wouldn’t say adult, I guess more teen. It kind of set the tone of the show. No, I wanted it to be kind of kid friendly but see what we could get away with.
So in this case, it's not merely that a gay character was in the show... it sounds like activism was the point.
Given the demographic makeup of the characters, they swung the pendulum in the other direction when it comes to societally proportional representation.
As I noted from the synopsis of the show earlier. 80% of the main characters non-cis/non-straight...that doesn't represent demographic reality either.
