imagine trying to explain to aliens from another planet 500 years from now why 500 years ago we decided to a.) include skin tone modifiers to begin with and b.) only allow for the gradation of skin colors that we do. beyond ridiculous.
EDIT: I forgot to mention how insanely ridiculous it is that we have these skin tone modifiers, but they don't even work for all "people" emoji, because of the obvious issue of rendering cartoon human faces in a way that isn't considered a racist caricature for many races. this makes sense of course, but I can't understand why, when this argument came up, they didn't just choose to scrap the whole idea instead of implementing it and restricting it to a subset of "people" emoji.
