Fem and woman aren’t synonyms. How else would you describe someone who was AMAB but is librafem, isn’t a woman and even further from being a man, but still has a connection to femininity?
Lots of transfem people are women, but its sorta like a rectangle and square (all squares are rectangles, but only some rectangles are squares). Practically all trans woman are transfem, but not all transfem people are women.
A feminine gender identity is equivalent to womanhood. People who identify as feminine are also women to some extent even if they don’t call themselves women, this is especially true for trans women who are in-denial of their transness (i.e. people who claim to be femboys yet want boobs and pretty faces).
(This is incorrect.)
Since you say so, you must know what a gender identity is. Tell me then, what is gender? What principle makes something a gender, or not a gender?
A gender identity is male, female, nonbinary, and various combinations of male + nonbinary and female + nonbinary (demiboy demigirl etc.) a gender identity is not male + female or male + female + nonbinary (bigender and trigender is not valid gender identity) a gender identity is also not wanting to be an inanimate object, mythical creature, or non-human animals, Xenogenders are an insult to the trans community and what it means to be transgender. If you say your pronouns are catself, dollself, demonself or anything else stupid like that I will not only not use them I will make fun of you for being a sad pathetic piece of shit human who pretends to be trans because he/she finds it so hip and cool, fuck you for appropriating trans experiences.
