Aibu to think what colour emojis someone uses doesn't matter?
My friend, who is mixed race, had his emojis default to a black skin tone. He used this (the thumbs up), but was then told off by a colleague as he wasn't 'dark enough' to use this, by a black colleague. He thought it was ok, as he wasn't being disrespectful, and his background is not white either.
I have known people who are white use black emojis too, maybe as a sign of solidarity.
Personally, I couldn't care less what colour people choose to use. Or do you think people need to match their emojis to their skin tone precisely?
