obviously very few cis women put effort into appearing female
Right, so when cis women shave their faces, shave their bodies, put on makeup, have their hair done in flattering ways, wear clothes that flatter their figure... they aren't putting effort into appearing female? That's not what that is? So the only differences are a few mannerisms [citation needed] and bodies, both of which trans women can easily affect too? That's what HRT is for. Fwiw I haven't made any mannerism changes really. Trans women can also still be gendered correctly whilst not putting in a ton of effort. There is no difference there. We all pass as female the same way. (By bowing to cisnormativity and unrealistic beauty standards)
You dodged the question, though - I'm interested in what you see as the essential woman-ness of her sisters that she lacks.
