On "Ethnicity"

It's recently come to my attention that this whole "ethnicity" thing may not quite be what everyone seems to have been trying to get at.

At least according to our (NZ) own government:

"Ethnicity is a measure of cultural affiliation. It is not a measure of race, ancestry, nationality, or citizenship. Ethnicity is self perceived."

🤯

In which case, I really should have ignored what all those silly forms have been saying over the years with their misleading categories, and just said:
"New Zealander"

And if really pressed further (if a long form box shows up):
"New Zealander first and foremost. A New Zealand born Hong Konger perhaps. But most definitely, not really 'Chinese', in the conventional sense of that loaded term..."

Guess what the forms usually really want to try to get me to say though... 🙄
