@Mind of tempest you claimed:
And when asked why you keep repeating this nonsense you replied:
Fortunately for everyone it is possible to look at what Halflings are actually presented as -
there's a D&D Beyond entry for the halfling:
You appear to have only partially read the first sentence which states: "
The comforts of home are the goals of most halflings’ lives:..." Note the word most. Which means not all and it means that they have goals beyond that. And if you had read the
second sentence "
others form nomadic bands that travel constantly, lured by the open road and the wide horizon to discover the wonders of new lands and peoples" which is a motivation - seeking to discover wonders whether in terms of lands or people.
We have not just one but five motivations given in the "Kind and Curious" paragraph. "
Even adventurers among them usually venture into the world for reasons of community, friendship, wanderlust, or curiosity. ... Halflings are easily moved to pity and hate to see any living thing suffer." None of these are good motivations to become a dark lord but all of them are good reasons to become an adventurer and want to stop a dark lord even if it means not going home for years.
So there. Halflings have more goals than getting back home. You personally might not
like them but those are all motivations.
And there is a core reason that halflings have a narrative space of their own but it's not one that can be covered by gnomes even if the space gnomes are in should be covered by halflings. And a reason why rock gnomes should be halflings and not gnomes.
The fundamental pitch of almost all the D&D races except halflings is "I'm cool and powerful and here's how." This includes the small but inherently magical gnomes. The pitch for halflings is "I'm an ordinary person, smaller, weaker, and less powerful than everyone around me, and easily overlooked. And I'm not going to let that stop me doing what needs to be done."
The central gnome pitch is, in most cases, undermined by gnomes being a separate species from halflings. "I'm small but magically mighty because I'm a gnome so everyone is going to know I'm magically mighty. And I'm a trickster who everyone can tell is a trickster by looking at me because I'm a gnome." The first one can be done roughly as well by halflings (always depending on stats); "I'm small but magically mighty and everyone knows I'm magically mighty because thanks to my cantrips my eyes always glow". And tricksters who are known as tricksters before they open their mouth have ... issues.
Halflings might not feature much in the deeds of the great or the good - but eliminating them would be like eliminating human peasants on the grounds they don't do that much either. (The rock gnome is an artisan type halfling). They aren't a race for DM worldbuilders but for specific types of players and characters.
