Elaborate on your gues insted of trying to prove me wrong as it is going off topic.
You continuing to reply to me like this isn't helping that. :v
What more can I say though? I've already said that Unbirths being related to death doesn't make sense, because death isn't a prominent theme in KH. Even if it means they're being reborn, that still doesn't seem like something that would be used in a series directed towards children.
People are focusing too much on the word 'birth' and don't think that maybe it's not referring to actual childbirth, but something else. Because they only think of the former, that's why all these theories come up with people trying to link the Unbirths to stillborn children and the dead.
