Lmao in a society that prioritizes het relationships of any kind, a bi girl character getting with a man is in no way radical lgbt representation. That is bi phobic.
A bi character referring to themselves as bi, living with their bisexuality, aka pride events, lgbt community service, etc, that is proper bi and lgbt representation.
In a society that prioritizes cishet relationships, and actively demonizes cisgay and transgay relationships, a bisexual girl character getting with a man is biphobic, and LGBTphobic.
Or, in the words you’re trying to shove into our collective gay mouths, “It’s not gay enough.”
