At this point you just seem like you're being willfully obtuse, but I'll try one more time. Second paragraph first. I was describing the personal qualities best exemplified by most halflings and that the halfling culture values most highly. It describes what you would expect to see or how you would expect to be treated in a typical halfling village. And I don't think my description strayed too far from what's in the PHB.
The PHB also describes (and it seems weird to have to explain this) the personal qualities that the dragonborn culture values most, and their values as a culture are much different than those of the halfling culture, and as such, a typical dragonborn village would have a much different character than a typical halfling village. Do you agree?
You can call me fantasy racist if you want, but yes, I think that any character that had any knowledge of dragonborn culture, that met a hippy dippy dragonborn character would think it was strange and might wonder why this guy is so easy going when most of the other dragonborn they have met are very stern and serious and very into swords and familial honor.
BUT, apart from reactions from NPCs, I would expect a player to role play an easygoing dragonborn differently than one would play an easy going halfling. BECAUSE a hippy dragonborn commune is subversive. A laid back halfling shire is typical.
