Is There a Dialectic for Womanhood?

A woman is somebody who identifies as an adult human female. And a man, correspondingly, is somebody who inhabits the associated masculine role,. If it was defined by role, then presumably it could change with time as rolles shifted. Some philosophers like katherine jenkins have argued that womanhood should now apply to any one who has the gender identity of a woman. So that makes it easier for male bodied people who are trans gender to countas women. It can be quite complicated to articulate why that's a good thing.
