Don’t think GP is having an issue with a +1 from a black coworker, rather that the coworker had reacted in slack using a black thumbs up. So GP didn’t want to click the black thumbs up to react using the same emoji, because GP didn’t think that a black thumbs up represented him, and would rather react with a yellow or white thumbs up. GP is then just saying that non-white coworkers probably feel the same about the yellow thumbs up emoji. Ultimately using emoji is about expressing oneself, and skin colour is a big part of peoples identity (for better or worse). So it makes sense that they want their expressions using emoji to represent their identity.
