Feathered, I can only assume you've never operated into or out of a French airport.
Why would you assume that? I learned to fly operating out of (and into) French airports.
I understand that you feel more comfortable/safer when flying and talking in your native tongue. It's hardly arrogance at all--we are in complete agreement. I feel the same way.
Ignoring the ignorant "forgiven" comment, the future primary comm will likely be computer/text based rather than voice anyway. Consider the 'situational awareness' implications.
