No, that's not what I said. What I did say:
At some point you did not exist. You were not a person, or a fetus, or anything. You were nothing. That changed.
You said - "You were once not a person."
Now you say that "I was nothing."
I was, and I was nothing?
How does that work??
You still need to explain how birth renders personhood to a being.
According to you, five minutes before you were born, you were not a person; and then once you were born, you became a person. Can you explain the reasoning behind this? What has changed in those five minutes, that almost magically turned you from a non-person to a person?
On the whole, you are simply talking about a specific
legal understanding of personhood, but not an ontological one.
The legal understanding of personhood is arbitrary, it changes over time - slaves, for example, were usually not considered legal persons. In some slavery systems, a person could become a slave, lose their legal personhood rights, and then buy themselves out, becoming a legal person again.
So legal personhood is a very relative phenomenon.
What is more relevant is ontological personhood - this one should not be relative.
