I find it highly ironic that people complain about drag queens and trans women performing regressive stereotypes of women, and yet have no problem with women performing the same stereotypes.
The whole thread is an attack on a woman doing something stereotypically feminine, in response to a certain kind of pressure that disproportionately affects women, since everyone knows who the women are when it suits them. By distinguishing women from transwomen and drag queens here, you're demonstrating that you know the difference too.
However, the point is that doing stereotypical woman things isn't what makes Lauren a woman. If she'd never had any work done, if she weren't beautiful, if she had one leg, if she were black, white, gay, straight, fat, thin, a SAHM, a world leader, stupid, a genius, whatever, she'd be a woman. It is not something you perform, it is something you are. Similarly, a drag queen ir transwomen could act out every single female stereotype that there is and he'd still be a man. You have to be a man to be a drag queen or transwoman. It's literally the only requirement for eligibility.
It is far more regressive to say that he becomes a woman by acting out these stereotypes because then you are asserting that performing these stereotypes are what make him a woman. Actual womanhood is not a collection of stereotypes and Lauren would be a woman if she'd never had anything done.
