No, it doesn't consider humanoids to be the only beings that can be "persons". The names of these spells were picked out decades ago, back when Elves didn't have souls and the game referred to demi-humans. It isn't called "Hold Person" because it only works on those with personhood. It is called Hold Person because it was designed back when the game was less defined and they needed to make a version of the spell that worked on a bandit, but not a dragon.
The point I was making (and the reason I
specified the name of the spell) was that Hold Person's name is problematic if they don't want it to be making a statement about personhood with it. I'm aware that wasn't the intent, but it hasn't been targeting by body shape for a while... so the name stands out more.
It also wasn't my primary example, which you completely ignored.
NO WHERE in the game will you find any of the creature types defined in such a way
Two things:
1. The types themselves have no rules or definitions at all. Everything in 5e that "defines" what creature types "mean" is built into the other systems that interface with them, not the types themselves. E.G., you wouldn't have "Undead are vulnerable to radiant damage," you'd have "Vulnerabilities: Radiant" in some undead stat blocks.
2. Ignoring the wording of Ceremony in your reply to me doesn't make the assumption it is making - and the implications it has for the types it interfaces with - cease to be 'somewhere' in the game.
I can only really conclude here that you have not been responding to me in good faith from the moment you decided to accuse me of being the source of what I was complaining about. I do not appreciate you making this about some "personal problem" you accuse me of having.
There are, whether you like it or not, parts of the game with these implications. They are mostly relics of things designed for different paradigms than what they currently exist in, but they do exist. That wording of Ceremony was printed in Xanathar's - it's not some ancient niche thing I'm making up, and whatever "personal problem" you think I have didn't manifest it into RAW.
