So are you saying that beyond genitalia there are no inherent differences between males and females?
I'm saying that beyond genitalia there are no essential differences, only tendencies/average differences, which you cannot use to make a clear male-female distinction since they form a statistical distribution that overlaps a great deal with male characteristics. So yes, women on average are less muscular than men, for example, but you can't use a certain degree of muscularity as a qualifying or disqualifying factor for womanhood, since there are women who are more muscular than the average man.
