Or is it more that the presence of female genitalia is irrelevant if one is too tall/wide/muscular/good/successful/unattractive to actually be a woman?

Your sister who is a delivery room nurse has no idea what happens to the infant once it leaves the delivery room. Nobody gets genital surgery in the delivery room.

If you care to read on the complexities of phenotype vs genotype here is a clear explanation

Maybe they think they can win? Many can and have. Maybe they will succede!
