Space

Space, I think your confusion is conflating 'masculine vs feminine' with 'man vs woman'. It's a pedantic esoteric distinction but it exists. "Man vs Woman" is gender roles. Women do this men do that. Masculine and feminine just describes different ways of behaving and appearing. You can still have genders without roles. Kinda like the pretty young lady in the science lab and all that ****.

Also according to feminist theories, space, it could be called a literal crime to disrespect bananself's wishes. 

Nobody is arguing for abolition of any genders tho

Transgender and Transexual people imo are in the same general area. They want to identify with different sexs than the one they were originally born with. If I speak to someone that is transgender or transsexual don't take offense if I call you by your original gender or name or whatever. I call people what they were born with, it's the same with nicknames i call people by their birth name.
