I agree with your point (moreso than with the article itself), and I would add that growing up as a member of a "traditional" ethnic minority in a country also gives you extra perspectives (even besides the automatic learning of two languages). This is far from obvious, many of my peers as I grew up saw it as a handicap or as a misfortune that they were supposed to learn two languages and cultures. I say, unless you are facing serious discrimination and as long as you have decent opportunities of practicing both languages, it is a great advantage. Besides language, another thing I see as advantage is a natural skepticism towards nationalism and all sorts of "rallying" behind a flag (unless you find yourself locked into the mini-nationalism of your own group.) Growing up in minority you realize that countries are artificial constructs, not the most important in the greater scheme of things, that ethnic/linguistic identities are not nearly as absolute as they are made to seem, etc. etc.
