You're making this horribly difficult on PG. I think legally nobody has an ethnicity - we only have nationalities (which while you may disagree is a positive or useful attribute, still exists legally). In some countries (like say, Hong Kong and China) they ask you for your race. I write down 'Canadian'.

It's this type of issue I am asking about. My friends all call me Chinese and I make a point to call myself Canadian. Am I ignoring a valid category in which I am a member regardless of 'denial' ?
