Let me give you mine:
Progressive personhood is a reality.
If you die before your birth, typically there is no investigation into the cause of your death.
If you die after birth, someone - even if just the coroner - will have to look into it.
-But at that point, you’re still very limited on the rights you enjoy. You’re largely under the control of your guardians.
When you turn 16, it is assumed you’re mature enough to drive a car.
(clipped for space)
After that, it’s potentially downhill, I’m afraid
Personhood is absolutely a progression. This is the reality in which we find ourselves.
