Tan,
I'm think you have no idea to whom you are talking to. I have been around ( that's outside north america) and belive me you are making a big mistake by assuming you have the only correct way of thinking.
So if we apply your statment to evrery contry in the world you would probably be baned from leaving yours. English is not the all mighty language out there it does'nt mean that beacause you speak english that every body as to. If you don't understand the communications aroud you then stay the hell out of there. If you think it's that dangerous then why are you still doiing it??????
You have to either, lead follow or get out of the way.
I'm fully bilingual and could'nt care less what if people speak french or english. I sugest you do the same thing. If it makes you that nervous and your not doiing anything to correct the situation you have a problem or just plain ignorant.
One last thing, I will tell you the same thing please refrain from making statments without the experence to back it up.!!!!!!
cheers.
