I'm afraid I've no idea what you mean by strong evidence "between the sexes".
*Very, very slowly*
Person A is a biological female who identifies as woman. In the common parlance both her gender and her sex are female (semantics of how widely and inconsistently those terms are used aside.)
Person B is a biological female but identifies as man.We're months into this discussion and people are still arguing for qualities that can turn a woman into a man but isn't required to just be a man.
Now we have to stop and make sure we are all on the same page before we continue.
There
has to be a meaningful, objective difference that actually exists independent of these two people's thoughts. If there isn't this whole thing collapses into the biggest nothingburger in history.
I don't care what you think the difference is, but you have to admit you think there is a difference. A difference, not a copout. No "Well it's complicated (and then never actually expand on that)," no "Well they think...," nothing but an actual, objective difference that exists in reality.
Again what that difference is I don't care at this point, I'm beyond that. But there is a difference. A sex-female who is a gender-woman has to be somehow distinct from a sex-female who is a gender-man or this whole thing is pointless.
Okay. So take whatever that difference is. Again don't care what it is at this this point. But just take what ever it is.
That difference. That exact same difference. Again no copouts where people just repeat "it's complicated" over and over with no intentions of ever going beyond that. That difference between a female who's a man and female who's a woman... has to also be a difference between a (for lack of a better term, I'll grant it's not perfect) traditional man and woman.
I'm sick of this... semi-permeable membrane of gender/sex identity that can somehow turn a woman into a man but doesn't exist as difference between male and female.
You, you, you, not me, you are the one arguing for meaningful, non-biological differences between the sexes.
