I like @yesitszen’s answer. Although, I might use ignorant instead of idiots to be nice.
@Suivre how are you defining white? And, why does it matter what color people think Brazilians are?
Also, in places like the United States of America, the people who mostly immigrate to America from Latin America have darker skin than your average Northern or western European. In fact, in America, a lot of people would even stereotype Italians as having a darker complexion and dark hair, because traditionally the Italians who first migrated here were from Sicily and Southern Italy.
It’s worth saying that in the US at least, the category of white as defined by our government, includes a lot of darker tones. My husband is white Hispanic. Some Americans might see him as not white, but the US government considers his race white on the census.
Furthermore, if someone is Russian-Mexican before winding up in the US, or German-Brazilian, a lot of people in the US ignore the stop over in Mexico or Brazil that the family made. When people find out my husband is Israeli, French, and Spanish, and Jewish, the second generation Mexican part seems to disappear for them. I tell them he is as much Mexican as I am American. Most people pause to think when I say that, and then most of them get it, and some people still don’t. Again, because of what @yesitszen said.
@Dutchess_III Brazil had a lot of black slaves brought into the country during the slave trade. Possibly, more than the US, I’m not sure. Definitely very big numbers compared to other South American countries. There are black people there, or part black from intermarriage etc.
