1/2 I'm in your ask box with lesbian PB shit, AGAIN. So there was a post in AT amino about how both PB and Marceline are bi, and there this was this comment: "Yes, she was a child again. 12? Not everybody knows they're lgbt+ as a kid/tween. She lost that attraction once she was older again. It can also be argued she only used him to return to normal". Just holy fucking shit.
2/2 And after I told that person how kids can be LGBT and that sexuality doesn't change with age, they said: lEsBiAnS cAn ThInK tHeY'E iN lOvE wItH mEn" and changed my definition of lesbian from "women who only attracted to women" to "non-men attracted to non-men*". And they in the end added: "and the feeling was friendship. Thank you for coming to my TED talk". I was at my fucking limit so I gave up and blocked them, didn't want to continue that.
That's annoying. I know some people hate when others say this, but sometimes it needs to be said: they're fictional characters. We could argue about what their "real" sexual orientation is all day. I think the easiest and most obvious answer is that she is bisexual.
Compulsive heterosexuality is a thing. But I also know women who thought they were lesbians, thought the men they dated were just due to comphet, but realized later they've been bisexual this entire time. It can go on forever. Even with historical people, we often don't know the true answer because life is complicated and we can't read anyone's mind. We don't know if their sexual orientation was straight forward their entire life, if they secretly were gay or bisexual, how accurate the words they were using at the time were to their actual sexual orientation.
I think trying to get so meta about something like this in children's fiction especially is unnecessary. And then there's the context of Adventure Time. Fictional characters don't live in our world. Comphet isn't really discussed--the culture and morals of the world are completely different; comphet might not even exist.
But again the argument is stupid and in cases like this I think what's the easiest and most obvious answer is best. PB and Marceline are bisexual. Also lesbians are women. Non-women cannot be lesbians.
