I wholeheartedly agree ...
Humans, on the whole, seem to be driven to exclusiveness. Forming clubs with special insignia, dress code, and language. Just look at the diversity in dialects within any language in any old, densely populated country.
Admittedly globalisation, and in particular radio and TV have led to some homogenisation. But I still think that we'll never have one "world language", and that's a good thing, too.
