On a different note, in the real world people wear these ear hats just because it's cute / fanciful / quirky. But if you were to wear one in this world and you didn't have animal ears to go under them, are you being racist?
Kind of like how a white person painting their face completely black (see
blackface) is considered racist now, but painting your face completely blue is just quirky (see
Blue Man Group) because there aren't people that are naturally blue.
