I've followed this thread with interest and dismay. As a native english, 9/10ths and 3/100ths language speaker, almost anything said in anything other than english goes right over my head, but the idea that it shouldn't be allowed just because I don't understand it, I find ludicrous, discriminatory and sad.

All the arguments in favour of an english-only PM seem to boil down to a single premise, "I might miss something", which is where the sad part comes in. I've also seen people get on this broken high-horse a few times when a couple of non-native english speakers greeted and exchanged pleasantries with each other in their native language in the CB. What is the problem? The CB frequently has several conversations going on at once on different subjects, and the participants in each simply ignore the others. Is it really that much harder to ignore stuff when you don't understand it? Or is there some other insecurity at play here?
