In the 15+ years I have been talking to people about abortion here are the terms that pro-birth people get wrong without fail:
Murder, as in "abortion is murder!"
Murder is a legal term defined as the unlawful killing of a human being with malice. Abortion does not involve malice, for starters. It is also debatable whether it is a human being. A human, yes, but a human being? Ehhh, not so much.
On that note: human being.
I will steal this from a Christian source for all you lovely religious pro-lifers:
The 7 Traits of Human Beings
Humans are created in the image and likeness of God. As humans, we interact and love each other. ...
Humans are called to happiness and holiness. ...
Humans are rational and free. ...
Humans are moral beings. ...
Humans have passions or feelings. ...
Humans are blessed with a conscience. ...
Humans are able to sin.
A fetus is unable to love or interact. They can not sin. They have no concept of morality or ability to rationalize. They have no feelings or passions. They simply float in the womb attached to the pregnant person hosting it. On this basis, a fetus or embryo is not a human being. Simply human.
Genocide
This term has a historical basis around the Armenian Genocide and the Holocaust, though genocide is much older than that. Genocide is the deliberate killing of a large number of people from a particular nation or ethnic group with the aim of destroying that nation or group.
Abortion does not have the aim to destroy an ethnic group or to destroy a nation or culture. Not by itself. It can be used as a tool within genocide, but that is not its function just as a steak knife can be used to stab someone, but you wouldn't call everyone holding a steak knife a murderer. Would you?
Bodily Autonomy
For something to have bodily autonomy, it must be autonomous. Which means: having the freedom to act independently. Within the context of bodily autonomy, it means that you would not gain bodily autonomy until after birth because it is only then that the body is independent. The baby will need help, but it is no longer limited to needing the sole help of the body it resides in. https://www.unfpa.org/news/bodily-autonomy-busting-7-myths-undermine-individual-rights-and-freedoms
It's easy to remember with FRIES.
It is not coerced or pressured. It can not be fear driven. It should involve open communication and can be revoked.
It is through consent that we have a civil and healthy community.
