Seems to me Elaine, by talking only about women, NB females - can't think how else to say it- & transmen, is highlighting that post-genital surgery TW are NOT like us. All they can aim for is a passable imitation of female genitals. And if the post-op aren't like women, the 'pre-op' certainly aren't going to be.
A neo-vagina is not the same as a vagina, it does not have the same structure nor the same abilities. Think of the astonishing stretching the vagina undergoes during birth. Every time someone like Elaine discusses female anatomy and physiology they bring the differences to the fore. And transwomen hate that.
