In my second paragraph, I mention 50E6 current students. Many of them will take spanish lessons. All of them reside in the US. Let's say only 50% does that, we'll be talking 25E6 with english (sic) as 2nd language.

You can prove almost anything if you get to invent your own facts.

There are over 4 million children in Venezuela. All of them reside in Venezuela. Let's say only 50% take English lessons. That's 2 Million extra English speakers.

But wait, for every English/Spanish bilingual, you add a number to both the English column and the Spanish column. So its a wash.

I also mention a reference to some 41E6 hispanic US residents.

What kind of funny math are you trying to use here? Those 41 million are already counted among the Spanish speakers (whether as a first or second language). Adding them in means you're double counting. What we really need to further the debate is a source which measures growth rate of languages, and maybe a human interest story about what they're teaching as second languages in India and China.
