On a more humorous note, I can imagine gangs of Elmali and Yelmalions hurling insults at each other about why the other's god is such a wimp.
"Your god is just Orlanth's lackey!"
"Well, your god is Yelm's stooge! And we get fire magic!"
"Yeah, well we get Sunspears!"
"Only from his old man, not from him!"
Etc, etc.
