I had two college roommates one was a full blooded native american, the other was a dude with achondroplasia, and I am a giant.
Pretty sure we could've gone adventuring together.
Anyway, Dwarves are just people with a handicap, some cool some not. When I was a teenager there was this old guy (who had some form of dwarfism) that came into the comic/gaming shop I worked at frequently to haggle over prices of just about everything in the store. He was annoying and just as much a jerk as anyone else.
