If you label latinos as literally anything at all, be it white, black, brown, or anything else, youre ignorant.
Latinos come in every race imaginable due to complex racial mixtures, each latino country different from the last. I personally myself am a Puerto Rican with a white Puerto Rican mother and a black Puerto Rican father. My friends joke about me looking hispanic but if they were to look at my parents, they wouldnt say the same thing.
Surprise surprise, Latino is not a race of people. Its more about the culture.
A latinos race should be decided at an individuals level, identifying as white, black, or mixed accordingly. But saying that just because they come from an island or Mexico means theyre black is ridiculous.
Look at Jennifer Lopez, Ricky Martin, and Tito Trinidad and tell me that theyre all the same race. Theyre not, lol. But theyre all Puerto Rican.
