I don’t think it doesn’t exist, it sounds silly but there’s clearly a difference not just in thinking but in how you feel what kind of emotions between what is masculine and feminine. as with all forms of sexual dymorphism, it warries, and a lot of cis women would in many parts not “soul pass”. it seems to me soul passing is the most warried form of dymorphism, unlike most parts of appearance cis women can just exhibit very very masculine traits here and it’s not unusual or seen as freakish by society. (which is good btw, even if I think most behaviour I’d consider masculine here is harmful or counterproductive or antisocial)

no I think it’s pointless kuz it doesn’t matter if you’re a trans woman and soul pass. at least in my experience, no one cares about that kind of passing from a trans woman. maybe if you’re stealth, but then you’d also get the allowed wiggle room cis women get to not have a perfectly feminine soul. so it’s kind of pointless, I don’t think cis people even consider the idea a trans woman could be a woman “for real”, and so just dismiss soul passing as either trickery or mental illness.
