I don't disagree the EO was poorly worded. But the "we are all female now" chorus is also wrong.
The pieces have the potential for going either way, but at conception everyone is biologically female.
In what meaningful sense is a zygote that first develops into an undifferentiated embryo with bipotential gonads and both sets of ducts (one for male genitalia, one for female) "biologically female"? It is not. It's pure hokum, good for guffawing but not much else.
During pregnancy hormones cause the males to take a different path. In the absence of this change order you get a female.
You need a lot of signaling for an embryo to develop in the first place. Some more for male development, sure.
However, I think that if some of that male hormone signaling is knocked out, you do not get a healthy female, but for example a person with undescended, testes or streak gonads and a vagina sans uterus (Swyer syndrome and similar). Or a phallus, testes and also a uterus (PMDS).
All this further shows that the "we all start out as female" is very simplistic. We start out undifferentiated, and then hopefully develop into one of the two biological sexes with healthy, functional reproductive organs.
