Okay, look.
Let's just be clear what the real message of this thread is:
Halflings are not 'good' only if the following things are true.
You have hand tailored your world so they can't survive.
You purposefully interpret lack of fluff in some places to mean hallfings are literally defenseless while ignoring similar holes of other races.
You as DM, being literal overgod of the world just plain don't like halflings.
Like it is VERY tiring sitting her watching this worldbuilding exercise masquerading as a discussion on Flavor as Written. Yes, you can absolutely create a world that specifically destroys baseline PH halflings on demand while mysteriously letting everyone else live. Congratulations. Can we tailor build a world that destroys Raptorians now? I hate those guys.
I haven't tailored anything.
I also am not only referring to a lack of fluff, but explicitly listed fluff. Why am I supposed to ignore that the fluff tells us that they use rocks and sticks to defend themselves? What purpose does ignoring that serve except to highlight that it is a bit absurd to expect that to work.
And, I'm not ignoring holes in other races, at least not in terms of defense. Elves and dwarves are explicitly given ways to defend themselves, gnomes are well explained, dragonborn have excellent defense in their breath weapons, and while humans don't have anything explicit, they have much that we take for granted.
Of course their are human soldiers, they have kingdoms, trade routes, caravan guards, they are modeled after the real world and assuming that the king has guards doesn't change anything about the lore that is written. Sure, maybe you could argue that elves have no way to support their populations food needs, I'm sure we could tear into that, but the problem with halflings is a bit more troublesome.
Because if elves need food, well, they live in forests which means hunting and gathering is quite possible, and they have trade relations with other kingdoms, so they can buy what else they may need. They also have a magical tradition which could lend itself to magical solutions to lack of food. None of that is written, but none of that contradicts anything we know about elves.
Do halflings trade? I've been told both yes and no. If no, they have a problem. If yes, they have a different problem, which is that the defenses we are told they have aren't adequate. Except for "Their Goddess makes them lucky and actively protects them" which starts causing other believeability problems in the setting. And we can assume they have different defenses, but then we are directly contradicting the lore we have been provided with.
And I don't want to get rid of halflings. I find them near useless for my purposes, but I still put them in my world and fixed the problems with the lore. I have no problem with people doing that. I just take objection to the fact that people refuse to acknowledge that this lore has way too many plotholes.
