They should also create emojis for bearded people. And albinos. And people with acne. And freckles. And every combination of those. Because these people seem a wee bit underrepresented, and I want as much diversity in my emoticons as I can have, because current emoticons can't get their job done.
Skin tone is personal and being able to choose one's skin tone to represent themselves should not be an issue for you. No, skin tone does not equate with freckles, beards, and acne. People discriminate so adeptly on surface features but can't seem to discriminate at all when it comes to understanding any depth of intellect or ethic.
