Agreed. I also like the yellow-emoji option--use something that clearly has no race.

Except yellow skin has been historically used to describe Asians. Maybe purple or neon green could have been used to steer definitely clear of that.

If someone is tenuously making the "yellow emojis are actually asians" argument, they're certainly acting in bad faith, but I guess bad faith is what got us here in the first place. I find myself pretty unwilling to accommodate bad faith, especially because by definition bad faith will always make increasingly ridiculous demands.
