I'm saying that Tolkien took real life halflings with which he was familiar with, at least on principle, and imagined an entire race of them, and what they might be like. He took something that exists in reality, and modified it to his story. The rational basis for comparison between "regular" human movement rate and that of a dwarf, must either be based on reality, or on your own opinion. And if you base your opinions on analogs in real life, then you would probably conclude that dwarfs, gnomes, and halflings, should move slower than humans and elves.
The actual thing that's silly here is imagining the speed of leg motion of someone 3 feet tall compared to a 6 foot tall person, running with the same speed. That's comical, and actually quite offensive.
Giving halflings the same speed as humans is patronizing and offensive to me. It's anti-intellectual, has no basis in either reality OR fantasy, and I consider it not only an insult to D&D trying to assign reasonable values to such things like racial average speeds, but also to its players' intelligence. I find it insulting to consider playing a game where halflings, dwarves, and gnomes walk as quickly as humans, on the basis of communistic / socialistic everybody must be given a level playing field, because otherwise life is unfair and we can't have that. We can't recognize that. We can't admit that there are those with advantages and disadvantages, and that not everyone is created equal.
Because that would make D&D a game suitable for adults, instead of children.
Wow, Gorgoroth. You're really digging yourself in on this one. Read the room.
Halflings, Gnomes, and Dwarves are fantasy races created by fantasy gods in fantasy worlds, none of which really exist. They have magic and mysterious traits that cannot be defined in our real world. Darkvision, Lucky, Natural Illusionist, Stonecunning, among other traits. In a fantasy setting, these races are able to be defined according to the needs of the world, story, and the rules. If not game rules, then the rules of the divinities that crafted their beloved peoples.
There is nothing wrong with assuming that halflings are a spry race that take more steps with less effort and are able keep up the same pace as humans. It can be easily explained/justified that they were created with such boundless energy, or they evolved to suit their needs in a world populated by human-sized predators. Heck, one could justify that they need to eat a lot to support their high metabolism. Yay halfling foodie justification!.
It could easily be justified that while Dwarves may have to take more steps to keep up with a human's strides, they are able to because they have a robust stamina and just don't get tired as easily as a human.
Heck, a human can easily be 4 feet tall or 7 feet tall. In the real world, those people have different speeds. But in the game their speed is 30 feet because they are humans.
The designers gave Goblins and Kobolds speed 30 feet a while back now. So if there is a belief that most "smaller" races should be similar in speed, do we reduce the speed of the goblins and kobolds? Or bring the PC races up to par? I know what makes sense for player equitability.
It just makes sense to give these races a speed of 30, rather than try to justify all the penalties that smaller people "should" have.
If we keep them slow due to "justifying" penalties for smaller races, should we also reduce their space on the battlefield so they don't take up a 5-ft. square? Do we reduce their reach? Strength? Weapon size? With smaller heads/brains should they be less intelligent? Where does it stop?
Why not accept the fantasy? Accept that races can be defined more by the difference of their positive traits than any need to impose severe limitations on them.
... in my opinion.
