Somebody already did:
Might be, but they have not changed the declaration of human rights to use the word "person".
Why does that matter? Seriously though, why does the pedantic perspective matter here?
P1. IF a fetus is a human it has moral value just like the mother
P2. The right to life is more important than the right to privacy.
C. IF a fetus is a human then we must choose the lesser evil - banning abortion (exceptions being when the danger is too high)
No.. I don't accept that premise. That humans have inherent moral value. I've already explained why fetuses don't share the same value that borne or adult humans do. Please object to that instead of repeating yourself. Furthermore, a right to bodily autonomy is very different from the right to privacy. That's like saying the right to keep your organs is the "right of privacy. Blatantally false equivalence there.
I am saying that if abortion is immoral then it doesn't matter that women's rights are broken, as the right to life is more basic and fundamental. Also, we are prohibiting an industry, we will not in any way directly apply force on the mother. If abortion (exceptions excluded) are banned that is not "forcing" the mother to carry to term - nature forces her, we simply don't allow society and science to defy nature in an immoral way.
Appealing to nature - that's a fallacy called the naturalistic fallacy bud, I'm sure you knew that though. Furthermore, the mother had a choice, to abort the fetus, and you want to stop that by law, that essentially forcing the impregnated to carry the fetus. Please don't play pedantic games with me here, this is trying to strip people of rights to their body. Whether you want to acknowledge that or not is your buisness.
I do not think humans have intrinsic value
Still, society must ACT like humans have intrinsic value. If not, we get slavery, holocaust, oppression of women and children and lastly persecution based on religion.
A pragmatic argument? I don't see how that applies philosophically. You can't justify anything like that, it becomes an infinite regress, again, the sperm, the skin cells.
a speciest lens that made us only care for humans and not every species equally
Interesting question. But it is survival of the fittest, isn't it? Since animals can't really agree to a moral contract, AS A SPECIES, they cannot have the same moral considerations by your own definition, as they cannot respect the well being of others. Also, they are not part of society but live in the wild.
I don't think you understand how that works, we have a moral value for animals that is either none or much beneath humans, my point is that IF we were to use this framework without personhood or suffering, every species would be on equal moral ground as humans. Not a neccessarily bad take, but its the one you would be accepting if you disregard my arguments.
Are people not allowed to change their mind regarding such a huge decision and future impact on their own well-being?
Yes, they can change their mind. But action is not the same as though. I cannot be arrested for "wanting" someone to be dead, but I can from killing.
You have failed to demonstrate that fetuses have value or that it is murdering to abort them. You have gone on as if I've accepted the premise that they have value and that are being "murdered" yet I've made it clear I do not.
it is not moral to force a woman to donate, their body, mental state, and possibly their life if they do not agree to have a child.
Agreed. No force should be applied to her in addition to the burden she already has. And when she gives birth she is free to leave the child to be adopted or taken care of, as such, we can compensate her and also help the innocent child. This is, at the very least, the only moral choice in the 10% of cases after your 13 weeks brain-idea.
That isn't how society works, neither is how it works philosophically - you have already taken a large amount from the woman. Imagine this- "You will be tortured, you will be forced to have a camera shoved down your throat, and then you will be forced to feed it nutrients for 9 months, don't worry though, afterwards you'll get money and you can get rid of it." Please have basic decency.
