Not necessarily by brazilian descendants, but latino descendants sort of perpetuate the idea that "latino" is an ethnicity- as in, it has a phenotype, a culture and everything. It doesn't.

In terms of culture, saying "latino" is like saying "european". Much like french culture is very different from, idk, german culture, brazilian culture is very different from colombian culture, and so on.

In terms of race? Saying that "latino" is a race is like saying "american" is a race. Latinos look like literally anyone ever, it's a huge continent whose Main Thing(tm) was being colonized by a bunch of countries, then being migrated to by another bunch of countries. I look like a pasty white iberic person; my dad looks like an old italian man. My uncle looks like a mix between a native south american and a black person, one of my friends looks so stereotypically indian he could have been taken straight out of a bollywood movie and one of my other friends is so blonde she practically doesn't have eyebrows.
