So, I was talking (yelling) with (at) somebody about dwarves not being Scottish at all. They're either Germanic (Ring of the Nibelungen), Nordic, or somewhat derived from Medieval stereotypes of Jews (Tolkien, Pratchett).
Despite the fact that I'm clearly right, a huge number of nerds seem to have this idea that dwarves are supposed to talk in Scottish accents. Including Peter Jackson.
Anybody have any idea where this comes from?
