I posted the full lore text from the players handbook (and dndbeyond) earlier in this thread, but apparently no one read it (probably tl;dr).
Sorry about that, Piff. I must have read it upon first encountering this thread, but that is a while ago now. The (lame) excuse that I can offer is that the bit of text that I quoted is the part that really seems to counter the idea that barbarians can be Baldurians.
And I did just read the extra bit of lore you provided. If these texts represent official D&D lore, they do confirm that barbarians can not be city folk. Larian: It's patchin' time!
