I understand why you’d think that because we’re all inundated with American culture no matter where we are in the western world. But that’s just not true. There are plenty of interesting groups who celebrate cultural identities not based on the country they live in.

A web search uncovered German-Brazilians and Italian-Argentines for me, I’m sure there are many many more.

No not hateful, you’re just giving off a weird vibe about it. But you’re half way there actually, transform that energy into curiosity.

The two you picked especially have a real fascinating history and I’d encourage you to check it out because both of those groups had a tough time in their early immigration days. They aren’t fetishising at all - those communities had to stick together because they weren’t exactly welcome, and that mentality became ingrained. Over time, it was less necessary for survival so it transitioned into more of a cultural tradition.

What’s with the negativity from you and the other comments?

I can tell you why Americans care. Because identity matters to people. The story of the melting pot is central to the American story as a nation of immigrants (even today) and central to individual identities. Thus, there is a lot of interest in backgrounds and geneology. If you ask the average American about their heritage you’re likely to get a surprising answer - so people talk about it more.

I get why it seems weird to many other cultures - if you ask the average French person (for example) their heritage they’ll say ‘French as far back as we can tell’.

The French person celebrates their identity through the lens of the French story, and the American does too, it’s just that the American story is the immigrant story.

I hope you do actually care. I hope in this era of rising nationalism and online hate enough of us value diversity of backgrounds and ancestries.
