It gets extra-spicy when editors start debating what nationality a person was, using names of countries which didn't even exist when the subject of the article was alive (e.g. people born in Central/Eastern Europe before WWI).

If you like your wikipedia spicy, you may enjoy the story of Croatian-language wikipedia: https://en.wikipedia.org/wiki/Croatian_Wikipedia

Or like when someone says they are from Punjab.

I was born in A, my wife born in B. Along life’s journey I picked up nationality C. We now live in D, where our child was born. Due to the rules of D, our child has nationality C. I can’t wait to join an edit struggle over their Wikipedia page.

I don't think a person who by their own admission picks up nationality like some curio at a flea market is a reliable guide. Voting for preëmptive ban in case their offspring passes the threshold for WP:Notability some time in the future.

I've noticed that when talking about national teams the BBC has started to refer to things like "the England team" and "the England player" to get around the potential controversy of calling someone "English". And I don't say that to disagree - I think that's probably a better formulation given the relatively recent global freedom of movement, and lack of control that young sportspeople have over where their parents bring them to live.
