Let's say we forget the "potential person" verbiage.
You wake up tomorrow after a night of heavy drinking, and find that there is now a midget with a genius IQ living in your abdomen, intricately interconnected with your own organs.
She says you agreed to this sometime last night, and will need to hang out there for the next nine months. The only way to remove her would result in her death.
What do you do?
If I were to give you the benefit of the doubt, I'd say you've bought the lies of the liberal abortion defenders and have their perspective when considering matters regarding abortion on demand. If you're going to use the term 'slavery', use it correctly; forced servitude is not the relationship of fetal aged child and life supporting mother because the child is there by invitation, albeit in most cases a very tenuous invitation due to ignoring the likelihood of becoming a mother when engaging voluntarily in sexual intercourse.
You might get an eyeopener if you were to consider that the same folks using terms like slavery when defending abortion on demand are quick to defend lab conception of embryonic age humans and dissection of these alive individuals at their earliest age, to get their body parts for experimentation and medical treatments yet to be defined specifically. but then, once you accomplish the dehumanization of a class of human beings, you may do with them as you desire, with no thought to their humanity merely their utility.
