if i might attempt to rephrase
@EzekielRaiden question because i don't think you've answered what you were asked, in a scenario where dragonborn, tieflings and aarakockra are the 'standard citizens' of a setting where functionally no humans or similar equivilants exist, what is preventing them from being 'relatable' when all that fundamentally differentiates them from humans are some ultimately superficial physiological differences, in comparison to species like elves and dwarves who possess lifespans that are multiple generations longer than humans, a factor that is much more likely to place psychological distance between them and humans yet you claim are somehow 'more relatable'.
