What I won't do is use language like "real women" that implies that trans women aren't really women. We are. We're just different from other women in certain respects.
But you are different from women in the one way that connects and defines all women - irrespective of race, religion, age, culture, beauty, size, education, beliefs, personality - adult human female.
Acknowledging this doesn't compromise our inherent femininity; in fact caring about the needs of others is an inherently feminine trait
My father was an early widower and brought up my brother and I. The most caring man I have ever met. Caring for others is not a restricted feminine trait or makes anyone a woman.
The word woman is just fine.
