REBUTTALS:
P1: Humans value their own well-being
Correct.
1. Can you prove that a baby cannot have well being?
2. A baby right before and right after birth are basically the same. Is post-birth abortion acceptable? What about child murder?
3. Well being is an ill-defined term. Well-being
P2: If you desire others to respect your well-being you ought to respect theirs
1. Not necessarily. Hitler did not "ought" to respect other peoples well being.
2. Animals can also have well-being, but we still do not think that hunting is immoral. We would never put an animal as more valuable than actual humans?
3. What does "respect" mean in this case? Its a substitute for moral duty, not an explanation for it.
4. This allows for people to be immoral if they do not desire their well being to be respected.
Con: Therefore you ought to value well-being
This is exactly what you said in P1. - your logic is circular.
CRITIQUE:
this system is dependent on human personhood
It is based on a feeling animals can have but many humans do not have. A rat can have the well-being a human baby cannot have (according to pro-choice arguments).
without personhood murder is not wrong, nothing is wrong, because there is no foundation for morality
This is exactly what Hitler thought, he called the Jews insects and rats, and by doing that he removed their personhood - then he killed them in the absence of human rights.
forcing the impregnated to keep their fetus and violate their bodily anatomy
I have bodily autonomy, I could kill people. Would you force me to stop and violate my bodily anatomy?
is you claiming that terminating a fetus or embryo is inherently more wrong
Yes. Killing a human being, even if that human being is not as developed as me, is morally wrong.
CONCLUSION:
without personhood murder is not wrong, nothing is wrong, because there is no foundation for morality
Exactly - this moral theory can allow abortion as morally permissible.
Under this theory, a society can choose which humans should deserve human rights and who should not - by choosing who is a "person" and whom to call "animal/fetus/etc"
Conclusion: this theory does not support human rights. Therefore this theory fails to meet my criteria.
