That is a confusing comment. I think that you think that the term Latin American refers to a race, when it doesn't. There are black Latin Americans and there are white Latin Americans (and even Latin American communities of Japanese and Chinese descent).
It is not really confusing.
What do all Latinos share in common?
(1) Catholicism. Unless they have been Americanized into evangelical churches, which perhaps 10% have. But an almost superstitious Catholic Christiniaty is a hallmark of Latinos, and not the rest of Americans, including Irish, Italian and Polish Catholics. Latin Catholicism is of a different order. The Virgin of Guadelupe. Non-Latin Catholics perhaps know a detail or two. Latinos, even mis-behaving gang members, tattoo her on their back. Latin Catholicism reigns and rules the Latin heart.
(2) Iberian language. Yes, Brazilians speak Portuguese, so there is a slight wrinkle in the linguistic monotony of Latin America. However, most Latinos in the US come from Mexico and Central America and Cuba, and Puerto Rico. They are Spanish-Speaking Catholics.
(3) Amerindian heritage. Most Latinos are perfectly aware that they are Indian in origin. Mestizo, perhaps, but Indian nevertheless. They have the same sense of ENTITLEMENT to this land, all of it, all of the land of the Virgin of Guadelupe (who is the patroness of ALL of the Americas, including North America) that Amerindians within the US borders have. "Your ancestors came over on the Mayflower? Well, mine were here to greet them."
(4) Matriarchal property lines and family structures. Anglo-Saxon and German and Italian and Dutch and Polish Europe...all the places whence white Americans came...are all patriarchal and now, atomized. Latino families have always been community property places, all of them. Women have been equally vested in property since the Spanish first came, and before that, as among Amerindians everywhere, the family was centered around the female. One reason that Latinas tend to have children conceived out of wedlock is the great Latina family network that makes it relatively easy to raise another kid among aunts and cousinas, etc. Amerindians, though poor, mostly hate abortion, and it's not Christian either, necessarily. It's cultural to Amerindians, and reinforced by Catholicism.
Males are macho and even warlike and aggressive, but the female usually holds the property and the money. Women have always outlived men, and in community property lands, which all of Hispania America was, that meant widows with land. Read Dana's account of Mexican California circa 1835.
Those are very distinct cultural differences from the American mainstream, and they form a culture at least as old, and just as tough, as mainstream America. Latin Americans are distinct.
