Not so. For one, trans women are women, but are not biologically female. For another, being a woman is primarily about fulfilling a certain role in society, having a certain relationship to people based on your gender and theirs. That's got very little to do with biological sex. Like I said, there's nothing biological about wearing dresses. Kilts and skirts are virtually identical, but one of them is seen as very masculine and one of them is seen as very feminine.
