How often do the different Races inter-mingle with each other?

[PArcher]

The ARC guild leader is xenophobic towards everyone, although he seems to refer to archery as something only Wildwood elezen do well and should only be taught to other wildwood.

Not only do Gridanians hate Duskwights, they also don't like Seeker miqo'te

Luciane, the Guildleader, is not (she's trying to get everyone to work together), its Silvairre, one of the other members, who is sticking to traditional ways.

Its also Keepers the Gridanians hate, for good reason; many of the ones they meet are thieves and bandits and murderers (look at the gang in the South Shroud), and don't listen to/follow the Elementals (which could bring their wrath on the city).
