I dunno, this sort of language just bugs me. I don't 'own' my uterus, I have it. I was born with it. It is a part of me. I don't 'own' my eyeballs either. I was born with them, they are a part of me. I didn't go to the store and pick them out. I didn't pay for them. They belong to me.
it's the result of a culture in which the human body is just a commodity to sell and purchase under capitalism instead of an actual person. if one can exploit a woman for sex or reproduction, it stands to reason the woman is not her body, but parts attached to a nebulous concept of self.
