You're saying that people are the ethnicity of their parents. That's racist and one of the main declaration of the extremist-right-wing who hate immigrants and say there is an "invasion".
You are saying a racist thing, the question is you're doing accidentaly or not. And at this point I'm starting to think you're not misguided
He's saying it because that's how it works. Unless you want to think that the entire Italian state is racist because of the jus sanguinis ("right of blood") which is the current law in Italy (and many other states) when it comes to determining citizenship. According to the wikipedia:
Automatic Acquisition of Italian Citizenship:
Descent: Italian citizenship is automatically conferred on individuals born to an Italian parent, adhering to the principle of jus sanguinis.
Birth in Italy: Children born on Italian soil to stateless, unknown, or parents unable to transmit their nationality may acquire Italian citizenship, aligning partially with the principle of jus soli.
Acknowledgement or Legitimation: Children gain Italian citizenship through the acknowledgement or legitimation of an Italian mother or father.
Minor Children of Citizens: Children without Italian citizenship, including those legally adopted under Italian law, can acquire citizenship if a parent holds Italian citizenship. This provision applies from 27 April 1983.
Former Citizens: Former Italian citizens who previously renounced citizenship due to naturalization in another country can regain Italian citizenship after two years of residency in Italy. This provision was governed by the Citizenship Law 555 of 1912 until its replacement.

In short - one automatically become an Italian if at least one of their parents was Italian (works also if the child was adopted). If the child was born in Italy it works only if the parents were "stateless, unknown or unable to transmit their nationality".
That's why Mario Balotelli had to wait until 18 for his Italian citizenship, because while he was born in Italy his parents were not Italian, they were known to be Ghanaian. Therefore he had Ghanaian citizenship. His Italian foster parents never officially adopted him, so he wasn't granted citizenship through adoption.
It all fits, it's all there, that's how it simply works and there's nothing racist in it, you just don't want to accept it.
So how are you "english" and not Anglo/Saxon/Norman/Whatever? Would your kids, and the kids of your kids and so on be english till the end of time?
Why aren't you responding to these easy questions?
Since you so desperately need an answer I can help a little. At the time of Saxons and so on Poland was also divided into tribes which were later united in a single Polish state. Back then people referred to themselves with the tribe names. One was "of the Polanie" and other "of the Wiślanie" and so on. But, after the tribes were unified - the sense of ethnicity started to change. Tribes stopped to matter that much and people were just thinking of themselves as "of the [insert name of the region]". Then the early modern times arrived and the concept of nations and nationalities. People living in Poland noticed that they speak basically the same language, follow similar customs and feel united to other people within their state and different from other nations in other states. At that time no one really remembered to which tribe their ancestors belonged 800 years earlier because no one cared anymore. It wouldn't make any sense after all, since 800 years is a lot of time and every person who lived in the XIX century had more than 100 000 or more direct ancestors in the time of tribes, so all those XIX century people were a mix of dozen different tribes of Polish and even non-Polish origin, so it'd be difficult for them to track their origin to one particular tribe.
So - the genes simply travel down the line, transmitted from parents to kids. We can poetically call those genes "blood". 1000 years ago there were tribes and kids born in a tribe became members of that tribe. People married within the tribe, intermarried between different tribes and kept track of who is a member of which tribe. When tribes stopped to matter they forgot which tribe they belonged to (some forgot after 100 years, some after 200 years... it's a lot of time, especially when you're not a scholar, can't write/read and have to work hard on your farm). When the idea of nations emerged descendants of those people started to think that they are Polish. And therefore, just like in the time of tribes, kids born to Polish parents are Polish by "blood".
The kids in the future will still be Polish, as long as they will remember that their "blood" is Polish. It'd be difficult for them to consider themselves Polish if for 300 years they lived in Australia and had no idea they had any Polish ancestors after all. But, at the same time, there are millions of Poles in foreign countries, descendants of Poles who emigrated or were forcefully resettled by Russians who still remember their heritage and are part of the Polish nation and though they usually don't have Polish citizenship (as they were born in foreign countries without the Polish government's knowledge) they have the right to regain it without any problems as long as they will present a proof (document) that at least one of their parents or grandparents or two great-grandparents were Polish.
When Polish parents move to Italy and have kids - those kids will be Polish. Even if born in Italy, speaking Italian since the age of 2, eating pasta every day and not knowing the taste of żurek. That's how it works, since that's what both Polish and Italian law say. Parents were Polish - therefore kids are Polish according to Polish law. Nationality of the parents is known and they aren't Italian - kids aren't Italian according to Italian law. They can speak Italian fluently and know zero words in Polish and yet they will still be Polish, not Italian. That's what the law says.
They will become Italian if they get their citizenship through application, since Italian law states:
Continuous Residence: Individuals born in Italy to foreign parents who have continuously resided in Italy from birth to adulthood are eligible to apply for citizenship.
After that they will be Italians of Polish ancestry, but also Polish as well, since no one can take that away from them. And since they will be Italians (of Polish ancestry) now, their kids will automatically be Italians due to "blood", as they will be as Italian as any other.
I would suggest you to read a bit more about how it works and stop with this rather pointless distraction.
