Fancy Navigator.
You speak of narrow mindedness with regard to us complaining about French ATC speaking French.
How about narrow mindedness of the French involved in the killing of the Shorts 360 pilot at Paris who was cleared to enter the runway at CDG whilst the same controller cleared IN THE FRENCH LANGUAGE a French aircraft to take off on the same runway.
Had the controller spoken english then maybe the pilot would have had better spatial awareness and still be hear today.
However, as usual, French pride should over-ride any safety considerations.
The Germans, Dutch & Danish are happy to speak English and their controlling is to a very high standard. They don't seem to deem speaking english a threat to their cultural identity.
