What I am saying is that it is society's view of being female that is the problem, not the biological reality of being female.
Completely agree, it's GENDER that's the problem, and gender and sex have historically been interlinked.
So, the question of what women have in common with transwomen that we don't have in common with men, still remains unanswered?
Actually I answered that question repeatedly pages back. Does nobody read the thread these days?
Both natal and trans women are judged against standards of femininity. Men and trans men are judges against cultural standards of masculinity.
Trans women are judged as being not "womanly" enough, socially obligated to be more stereotypically "female" with reprisals for non-compliance, mocked or seen as defective for any deviation from the cultural standard, all in the she way as natal women.
And yet they are not held up against the standard of femininity because of what's in their pants, it's because of what they SAY they are; women. It's because of their GENDER, not their sex, and that is what we have in common with them that we do not share with men.
