Not to sound churlish… My heritage is Polish/Ukrainian (depending on pre/post WW2 borders, and only one generation back), Irish, Scottish, English, and quite possibly a smidgeon of French, if you go back far enough.
Each of those nations and cultures have offered plenty of value or produced people who did.
I could choose to be proud of any of them and likewise, link my identity to any of them but it has never occurred to me to do so because I’m Australian, first and foremost.
That, and I don’t have enough arms to wave that many flags.
We have a country, a culture, and a flag that’s ok to be proud of too. And it’s common to all of us.
