First of all, Latin America is Central America, not south america. Second of all Italy, Portugal, and Spain were among the first to establish regular trade with and "colonize" (read: STOLE) the New World. Third of all, White people tend to call people by erm...incorrect names for much longer than it's appropriate.
so we can confuse the little kids in school! Just like that planet Pluto, thats not really a planet, but is, but isn't!
