The word you are looking for is enthnicity. Enthnicity describes the (self-)perceived belonging to a population group. This is of course highly subjective.

There is undeniably perception of grouping in the US based on heritage, where it doesn’t really matter when your ancestors arrived, just from where. So from an American POV it makes sense to call him Italian, because he is in the same perceived group as all the people from Italy.

On the other hand from a European POV it doesn’t really matter, where your great grandparents come from. You are part of the US-Group, so you are American.

This is not an exclusive US Problem, but a general migration problem & it happens everywhere. Comments like yours are the reason, why people from migrated families feel like they are in-between cultures. Instead of writing snarky comments on the internet, just accept that your perception of ethnicity is part of your ethnicity and other people can have other perceptions.

Programmed emotional support isn’t new. ELIZA was written in 1966 & surprisingly effective given the crudeness of computers at the time

2 Letter TLDs are always country codes (and ccTLDs are always 2 Letters long). So moving them to another category is technically possible, but unprecedented and improbable.

Because they state that free healthcare is automatically bad healthcare. Which, as a general statement, is just wrong.

Free Healthcare is a broad term for dozens of different policies in dozens of different countries. Just because OP’s specific country has problems, doesn’t mean that every single implementation of free healthcare leads to bad healthcare. Also a similar rhetoric is used as a dog whistle by the far right in the USA.

Additionally they are using a specific question about their situation, to rant about a much broader topic. This soapboxing called behaviour is generally frowned upon.

So the comment in isolation is wrong, attention seeking & looks like written by someone who is something between a manchild, that is unable/unwilling to present a nuanced opinion, and a nazi. All of which are imho criteria for a downvote.
