When you use the word "considered,"you invite opinions. It depends on who is doing the considering.
Nationality, ethnicity, native language and citizenship have different definitions by different people. I ski in the Dolomites in Italy and people there might speak German (South Tirol) Italian or Ladin at home. They are all Italian citizens.

The phrase, "Latin people" has a long history. Technically, I believe it applies only to "The Latins," --- people who spoke Latin in antiquity --- and their descendants, but by extension to everyone today who speaks a Romance language at home.

Ladin is similar to Romansh. I believe they may be descended from ancient Italic languages and not Roman soldiers. Vulgar Latin was never a single language. Roman soldiers spoke various Italic languages. Even now, in Italy, not everyone speaks Italian.

My own genealogy relates to this situation. I am descended from Pierre Robert, a French-speaking person who came to what is now the US from Switzerland.
From church records:
Pierre Robert, II,
Birth date, December 30, 1655
Birthplace:St. Imier, Neuchatel Canton, Switzerland
Death date:1715
Place of death French Santee, St. James Parish, South Carolina, Presently in the United States
South Carolina people are like Chinese: We eat rice and worship our ancestors.
The Robert family was originally from Wales, but came through Switzerland because of religious persecution. They became Swiss, but the most important thing to them was that they were Huguenots. Being Swiss, Welsh and anything else was secondary. This is similar to the Puritans, who came to Plymouth through Netherlands.
What people "consider" may be very important.
The Nazi "considered" people to be Jews based on the number of Jewish grandparents. The Israeli "Law of return," based on Jewish tradition, "considers" a person to be a Jew if his mother was a Jew. It was possible to be considered to be a Jew by the Nazi, but rejected by the Jews because one Jewish grandparent was male. I knew such a person. I am glad he survived. He had a good sense of humor.
Israel has just joined the Association of Academies of the Spanish Language because of Ladino,
Judeo Spanish is still spoken in parts of Europe but it is not to be confused with Ladin.

Ladino is a recognized minority language in Bosnia and Herzegovina, France, Israel and Turkey.
