One can hardly condemn people for sticking to the easiest western language there is. I'm German, which is more complicated than English, so learning English came quite easy. French is even more complex than German, and it indeed was (and still is) a lot harder for me. If I had been raised English, I'm not sure if I would have been able to get a grasp on one of the other languages. Maybe spoken Mandarin, as it doesn't need much of a grammar or tenses...
