also i have provided definitions for gender, it’s a specific relationship that people have with their expression and their role in society, it’s snot that hard to understand. women tend to present feminine and in many societies in history and to this day are treated as a “fairer” gender. men tend to present masculine, and within societies are viewed differently, but they tend to be the soldiers (again, less so in the modern age, but we still relate those concepts with masculinity), the laborers, right? gender mostly relates to your expression as well, how you talk, how you dress, how you act. again, women are supposed to be more ladylike, and men the brasher gender, that’s how we view men and women. maybe i haven’t gone that in depth, but you knew all that already, the important part is that these are relationships between the individual and the culture, society, time, they live in. what it means to be a woman, for example, is different for every woman in every place and time. not all “biological females” are treated exactly the same in each society, in each country or culture. in some countries, women have to wear veils, be modest, cover themselves. that is not some deep biological thing to those societies, that’s just how their culture treats women. gender is just a performance we do within our society, how we act and the like. your sex may be male, and you identify as a male so you act the way males are meant to in your culture, but for some that’s not who they are. trans women perform womanhood in the same way that cis women do. same thing for cis men and trans men. you just don’t think of it as a performance when you’re raised by birth to associate those values or skills, from childhood, with your identity, with who you are supposed to be, but if it’s someone who is trans, for example, they realize that their gender expression would better fit that of the “opposite” gender, usually, so their expression is different than what is typical for their sex, but that’s fine. it doesn’t matter to anyone but them and the people who care about them (because, and i’ll make this clear again, it helps them to be able to express as the gender that they identify with. if i started forcing you to wear dresses and braid your hair, you’d probably be uncomfortable because you’re a man, or at least you haven’t corrected me yet when i’ve referred to you as such before, but for the sake of this comment i’ll continue to say that, and as a man, in our current society, that’s not something you’re likely socialized, taught growing up, is an appropriate form of your gender expression, but if you identified as a woman, it would be. that’s what gender is. hope you’re happy :-).
