In the 19th century, midget was a medical term referring to an extremely short but normally proportioned person (e.g., with growth hormone deficiency), and was used in contrast to dwarf, which denoted disproportionate shortness. Like many other older medical terms, as it became part of popular language it was usually used in a pejorative sense. When applied to a person who is extremely short, midget is now considered derogatory. The non-offensive term Little person has since replaced midget. According to the Little People of America the human definition of this term is stated as such "a medical or genetic condition that usually results in an adult height of 4'10" or shorter, among both men and women, although in some cases a person with a dwarfing condition may be slightly taller than that."
But the dwarves we had were happy to do it and they were well-paid. It could well be that the [complaining] dwarves in question were not asked and it could be a bit of jealousy.
