In a post on EN World commenting on the artwork for the cover of the second edition The One Ring rulebook, a commenter exclaims:

A female dwarf adventurer in Tolkien’s universe? No thank you. Too much against canon for me.

I really detest this kind of closed-minded grognardia. Anyone who bothers to study the canon of dwarves in Middle-Earth knows that, while they are rare, female dwarf adventurers are not a violation of canon.
