That's the same thing, they're a woman

That's a part of why Celeste, and Madeline as a character, now has a strong place to some trans gamers. She climbed the fucking mountain. She looked at her self doubt, her fear, the person in the mirror telling her she could never do it, never be that person, and did it. She overcame it.

Madeline is a woman, and writing her character off as "trans, not female" is writing off the impact that story has had for people climbing their own mountains.
