You are full of it. The Vietnamese here are some of the most conservative anti-Obama people in the U.S. My wife is Vietnamese and she says your language is crude and offensive.
I have several Vietnamese friends. They think ANY language, but theirs is harsh, crude and offensive. I laugh when I hear them say that other languages are not “musical” and “delicate”. I love them dearly, but realize I sound like an ogre when I speak, although I’ve always been told I have a very cultured speaking voice and it is light and full of laughter.
