Unless we are granting new rights that we don't give to anybody else, nothing you brought up is remotely relevant.The problem with this line of thinking is that although the uterus is part of your body, the fetus inside it is not part of your body. It is a separate entity with its own body that happens to be inside your body. Since the fetus is a separate entity, this opens a host of questions regarding what rights it might have, when those rights are granted, and how to weigh those rights against the woman's.
People get pregnant during protected sex too sometimes. Sometimes, the sex isn't even consensual.It's also difficult to say that the fetus violates your bodily autonomy, since you essentially invited it to take up residence in your uterus by having unprotected sex.
Consent to have sex is not necessarily consent to get pregnant. Consent to get pregnant is not necessarily consent to stay pregnant. So, it doesn't matter.
I wish people would actually learn what bodily autonomy is and isn't. It is not the right to anybody else's body: only your own. Even if we grant a fetus full bodily autonomy rights, it'd be irrelevant to whether or not a woman can have an abortion. Hell, we could grant a zygote full bodily autonomy rights at the moment of conception (I don't), and it wouldn't matter.Even if we ignore this and say that the key issue is that of bodily autonomy, you have to weigh the woman's right to bodily autonomy against the fetus's right to bodily autonomy, as having an abortion will kill it, and killing its body violates its bodily autonomy. If you claim that the fetus has no such right, yet once it's born, the baby will have that right, then you must establish a rule to determine when the fetus gains bodily autonomy rights, since your claim is that it doesn't have them from the beginning.
Bodily autonomy is the entire issue, lol.These problems are messy, so I think a much cleaner approach is to avoid the topic of bodily autonomy and instead focus on the topic of parental consent.
Respectfully, it's only messy for those suffering from cognitive dissonance after being presented with the fact that in a consistent world, a loss of bodily autonomy rights for pregnant people is a loss of bodily autonomy rights for everyone.
