Three dehumanising thing is really important.
Vaginas are I imagine to most people esp men associated with sex.
Having us described as people or bodies with vaginas all over the place must subconsciously firm up the link vagina > woman> sex.
Because no one reads the phrase bodies with vaginas and doesn't translate that in their head to women in order to understand what it's saying.
What is the more subtle impact of women and girls not being given names to encompass whole human people who are female. But increasingly described as bodies with certain reproductive organs. Ovaries wombs- the bodies that can grow and produce babies. Vaginas clitorises (clitori?) - the bodies that most men enjoy penetrating. Vagina even comes from Latin for sheath.. And is generally represented in diagrams inaccurately as a constantly open cavity.
