In a previous US Census I was visited by a Census taker who insisted on checking the box "white" for my race.
Not only did I tell her that I go by "human", I also put my hand on the questionnaire and challenged her to define the color of my skin.
Compared to the obviously white sheet of paper it was quite impossible to refer to me as white. Red, maybe brown. But even our toddler could see it wasn't white.
