As you can see, I respect you more: I spend some of my time to provide links for you as proofs. But nevermind, it's offtopic anyway. And it's not so important for me to argue about :)
On that matter, there are some languages which are clearly much more common (over twice as common) as second languages than native languages. English, French, Malay, and Swahili are obvious candidates for this: English is a common secondary language, well, everywhere; French is common second language in Africa; Swahili in East Africa, and Malay in Malaysia/Indonesia.
