Do you still identify as SA? Or is Latam their own thing now?
Brazil is unique in SA/Latin America. The country was colonized by Portugal, not Spain, remaining as a single country since 1600 (spanish american, on the other hand, has gone through many divisions). Despite some similarities, there are many cultural differences between Brazil and other Latin American countries, such as language, food, politics, race, and history. Many Brazilians do not identify themselves as "Latin Americans," but simply as "Brazilians" - a sui generis people on the continent. "South America" is just a geographical term without a strong cultural association.
