Here in New Zealand the exonym pākehā has been deprecated by many but some who are called pākehā like it.

Yes, some folks like exonyms. A German nickname for citizens of the USA is Ami 'Yank' (< Amerikaner). It is just a wee bit pejorative, but I like it, and when I lived in the Rhineland used it as a self-designation. Sometimes shocked the more sedate and politically correct. The area I lived in had been in the former British occupation zone. Older peole still talked about die Tommies.

Thanks for the link to that interesting article and welcome aboard.

Ceci n'est pas un seing.
