" Who are the real LATINS? As in which nationality{ies}? "?

I don't have a clue

just wanted 2 say hi..............contact

"Latin" was a language so it's logically reasonable to give priority to language in defining people as "Latins".

When people of whatever background learn and use a language it is the first major step in their becoming part of that language's culture. Most often this happens with immigrants and with conquered peoples. For example, people of ancient Britain who spoke Celtic languages learned English after the Anglo-Saxon conquests, and their descendants today are now fully culturally English.

Likewise, African slaves who spoke African languages such as Wa, Yoruba, and Mande learned the relevant European language from their masters, and their descendants today are Americans, Jamaicans, Cubans, etc; not Malians, Ghanaians, or Nigerians.

The "Latin" languages of Europe are those derived primarily from ancient Latin, i.e. French, Spanish, Portuguese, Italian, Romansch, and Romanian.

It is an interesting question whether a Mr Faustino or a Ms Campos living in, say, Manchester NH, and speaking only English can really be called "Latin" simply because of their ancestry.

In the end, I suggest it is largely a matter of self-identification and of acceptance by the group. If both are in place, why and how could anyone else object?

In regards to defining a person as Latino/Latina -

The word Latino/Latina is used to define those born or whose parents were born in Latin America. This includes people of all races whether they are white, black, mestizo, amerindian, asian, etc. Therefore, if a black person calls himself Latino he is letting you know that he or his parents were born in Latin America. Technically, this is correct.

You might now ask yourself, why is this region of the world called Latin America? Why have a reference to Latin culture?

Latin America was given its name by those who wanted to define the region in the Americas that was colonized by people whose language originated from the Latin language. This included people of Spanish, Portuguese, and French descent. Technically then, it is correct to call it Latin America.

In Conclusion:

The word Latino/Latina has evolved from referring to those who spoke Latin to those who are born or whose parents are born in Latin America. However, notice that both definitions do not give reference to race therefore your assumption that people of African ethnicity cannot define themselves as Latin is absurd. I'm sure there were people of African ethnicity who belonged to the Latin culture in Europe.
