i actually think it's an interesting thought exercise to look at calliope's passivity from a similar perspective as her belief in gendered classes, i.e. it's not entirely true and largely self imposed.

because, well, gendered classes were confirmed to be not true and a misunderstanding on her part, and looking at it it's pretty clear why the idea is appealing to her: cherubs already have their whole thing with duality, and extrapolating that cultural idea onto sburb as a whole makes sense for a character who spends her days in isolated misery with the only promised escape being the game. because, it's important to note, that for a lot of characters, and calliope especially, sburb isn't just a game, but a representation of fate and cosmic purpose.

especially with the way "fate" in homestuck works in time loops and self-fulfilling prophecies, the question is whether characters do certain things because they are fated to do it, or if they are fated to do it because they were going to do the thing anyway. and calliope's stance as a character who is aware of her mythological role before ever entering the game, this question becomes even more poignant: is she so passive because she is a muse, or does she know she is a muse and therefore act so passive? the differences between alt calliope and alpha timeline calliope are also relevant, considering the way alt calliope describes her predomination over caliborn is by "wearing him down", and this is the version of her that had no contact with the outside world. we could kind of view the difference as the calliope that fully committed to the passivity of her role, her loneliness, won while the calliope that tried to resist it by making friends with the alpha kids lost. and, yet, a the end of the day, "realizing your full potential as per sburb dictates" is clearly not a good thing, considering one of them went on to become a villainous, cold overseer and the other gets to hang out with friends and live a happy life.

calliope believing she is "forever fated to be the most passive" is a very comforting belief for her to have, because believing in her mythological role so dearly means she gets to give her misery a purpose. it means that if she gets really really good at doing nothing about her situation, she will get to fix it. it means her life will sort itself out, if she just accepts everything as it comes. i think this is what is actually cool about her character, and why more people should be critical of taking everything she says about sburb as fact - she is very biased! she was put in a situation specifically manufactured for her to die, and told that her cosmic purpose is to just take it, forever. i think calliope is very interesting as a character who's probably the most invested in the idea of a cosmic fate game despite being in probably the worst possible situation as a sburb player, in a comic with on the whole is very critical of sburb.

i think more people should be less trusting of the things she says about sburb, especially about her own classpect, is my overall point.
