But you do agree that personhood is actually a thing, right? You do recognize that some entities are persons? I mean, I assume you would agree that
@bilby is a person, and
@Toni is a person, even if you don't agree that I'm one?
And I'm betting you agree that non-personhood is a real thing too, right? Like, the keyboard I'm typing on isn't a person, wouldn't you agree?
If those two things are true, then there must exist an inflection point between them, some stage of transition from non-person to person - even if nobody can perfectly agree on where that curve is perfectly horizontal.
I bet if you put your mind to it, you could make a reasonable and logic estimate of the range within which the vast majority of other people looking at the same curve would agree that the it's
more or less horizontal. And I bet that such a range is not at the very extreme end of the curve.
