It's too late at night to comment on the rest of your post, but I just wanted to point out that a person who speaks English, Spanish, and French does not have 'all of the Americas top to bottom'. There's also that little chunk of land we call Brazil.
That said, I'm a hispanic with pretty white skin. Shame on the ad comms if they don't ask for "brown-skinned hispanics" if that's what they really want. They DO ask, however, "White - non-hispanic." Oh yeah, and I speak English and Spanish fluently, and was able to "latch on" to French when I was young. I speak Italian, too. By my count that's 4, but it still wasn't enough to overcome my cumulative GPA. I don't think I have a point. Just sayin'.
Oh yeah, I am planning to study Portuguese next. That way I really can conquer all of the Americas top to bottom. Haha.
By my count Spanish, Italian and French put together are about 2 languages, at most. Spanish and Italian are very largely very similar, and Portuguese as you also mentioned, is basically the sister language of Spanish; it wouldn't take much effort at all to learn Portuguese if you're coming from Spanish. That's like saying you can speak 3 languages because you can speak Danish, Swedish and Norwegian. Those 3 are probably about 90% the same language.
