The Ethical Basis for Bodily Domain and the Rights to Bodily Integrity:
Bodily Domain is the medically defined area of your body, a territory of sorts, owned and controlled specifically by you and ONLY by you.
It is your skin and the all the area within your skin, it includes your organs, your bones and your blood and the spaces in between.
You are the sole determiner of what happens to those organs, that blood, and even the space within the area of your Bodily Domain.
That is your right to Bodily Integrity, which is also referred to as Bodily Domain.
There are three basic categories that describe essentially every interaction that can be done between your Body and other things.
Intrusion, Occupation and Removal.
They are given negative names mainly because they are the self defensible rights within the Bodily Domain, Bodily Integrity, and Bodily Autonomy trio.
Self defensible means they are only negative if you yourself consider them negative, because if you consent to something, there is nothing to defend against.
Intrusion:
Intrusion is any entry into your Bodily Domain that is negatively viewed from your perspective.
This makes it a violation of your Bodily Domain rights, normally referred to as Bodily Integrity.
It covers everything from rape, to delivery of injury (bullets, knives) injection of poisons, diseases, even non harmful or beneficial substances can be seen as a violation if consent is not given.
Removal
Removal refers to the taking of anything from your body. It can cover your own organs and blood, or even artificial or foreign material in your body, like prosthetics or substances that you wish to keep within you.
It is also a violation of your Bodily Domain rights.
It covers everything from organ theft, to blood stealing, to nutrient leeching.
Occupation
Occupation refers to any continuous presence of material or presence of living things within your Bodily Domain that is unconsented to. And therefore a violation.
It covers everything from parasites, unwanted implants and pregnancies.
These are all things that no human being should be subjected to unless they themselves are causing a violation of the same set of ethical principles.
So Bodily Domain should only be violated if doing so will protect your own or the BD of others from being violated and/or end a current violation in progress.
If you are violating someone's BD, your own becomes forfeit if they decide to defend themselves from your actions, and their defense violates your BD.
In conclusion:
An unwanted fetus is violating a woman's BD.
There is no way around this.
The fetus has no call to do so as the woman has done nothing to violate the BD of the fetus.
Hence a fetus has no right to violate the woman's BD.
But the woman does have a right to do so to the fetus in response to its violation of her, especially since that is currently the only way to end its Occupation of her BD and Removal of her resources.
To not allow a woman to defend her BD rights violates a set of ethical principles that protect us from having our organs taken for others' use, to avoid being raped, to avoid being enslaved, to avoid having our bodies used as tools for the benefit of others.
To do so would strip the usefulness of society to the individual in terms of promoting survival and comfort.
It would make remaining within society less beneficial then leaving it, and to lose these ethical principles would degrade our society in many deterimental ways.
Therefore attempts to remove the right to abort from a woman is not only misogynistic, anti-woman's rights, and ethically unsupportable from a viewpoint that values human rights to their own body, it is also a self destructive view that endangers all of us.
