Yeah, much of Baldur's Gate is left to creative license. If you can describe it and most the audience buys it, you're good.
I ran a TT adventure called Horde of the Dragon Queen which had the Half-dragon villain go through the city in covered sedan chair to avoid a lynch mob. (FR didn't have dragonborn as common PCs until 4E, and that lore hung around.) That made me sit up and think. Unfortunately, the players never got a chance to even be in a position to rip the curtain down.

If I were to play a goblin, hobgoblin, drow, duergar, dragonborn or similar, I'd _want_ to be called out on occasion. The conflict and nuance would be why I chose such a character. Now they shouldn't play the same, there's distinction why drow and goblins aren't liked. There'd even be situations where someone's fine with drow but up in arms with goblins. The writers need to get into the heads of individual NPCs they script - and foreshadow!
