As always the correct term is whatever the individual person you're talking about prefers, which is 99% of the time just going to be their name unless there's a really good reason to discuss medical conditions

I've met some who find the term "little person" really condescending. Personally my default is either "short/really short people" since that's just using the terms by which we refer to everyone else, or person with dwarfism if there's a specific reason to have to discuss the group of people with the medical condition.

Really to me it seems like there's only one wrong answer, and that's the one oliveoil went with lmao
