I don't doubt your friends' temperaments for a minute...<quoted text>language differences have never thwarted trade
and no, my friends in and from Egypt are some of the most loving and peaceable people I have ever known, if you want to paint with a broad brush you should start with caucasians, the kkk is alive and well in America is an example they are "fine church going people"
but to negotiate trade requires a form of communication..
i.e. a common language.
I don't 'paint' anybody with any type brush, all I am saying
is the airlines would be in schtuk without one language, which
happens to be English.
I used the Welsh as an example, their language has had a revival, but, they will freely admit that to get on in life, it is desirable if not necessary to speak and write through the media of English.
