Someone could write a book about this. But in short, it has to do with the objectification of women and subordination of their desires and autonomy in favor of their perceived biological role as sexual/reproductive receptacles. Add to that a hefty dose of victim blaming and the assumption that consent is either implicit or irrelevant, and you've got either one, depending how you skin it. But I don't really think the anti-abortion culture and rape culture are fundamentally different. They're both products of fundamental attitudes towards women and what they're for. They're coming from exactly the same place.
I agree. The premise of a woman's mere existence is that her body is for "our" use first and foremost.
Not her actions.
Not her voice.
Not her decisions.
Her body in and of itself must exist for "our" use when we see fit. Her desire for her own bodily organs (in particular her reproductive system) are secondary, are selfish, are irresponsible.
She must defer her organs to an unborn fetus.
She must defer her organs to an out-of-control and aggressive predator if she did not take enough precautions. And she must take responsibility for having to defer her body in such a violent manner. Or for a spouse and do her "wifely duties" simply when it is wanted. If a spouse strays, the blame typically falls on a woman for not offering her body enough for her spouse's satisfaction.
She is only responsible enough for her organs as what somebody else wants from them.
According to the culture.
I see exactly where you're coming from, and I agree. I might add that a woman's body....just it's mere existence regardless of age, aesthetic, skin color, religious background, class, educational background....only belongs to her
within reason according to culture and prevailing norms. At a certain point, she is expected to defer the use of her bodily organs for somebody else's survival, benefit, or pleasure. But overall, her body is understood to belong to somebody else at some point in her life, and she is expected to understand that
and appreciate that.
To take ownership of her own body is considered a radical act.
To take ownership of her own body
without apology is considered naive, myopic, scandalous, selfish, and irresponsible.
Hence, rape culture.
