Here is a sad fact! If anyone needs a ghost writer, it means that they may not have the command of the Queen's language the way that they do their own language. This is a resultant of being oppressed by a group which does not speak your own language.
We have fallen in love with the language of our oppressors and hate our language to a point where we think that a comment like the one you made is actually an insult.

The Chinese are so proud of who they are that they will require an interpreter instead of speaking the foreign language, as a matter of principle. 

The true insult here is that she not only had to divert from her own language but aimed to communicate in a foreign language and even respected it enough to enlist the help of a ghost writer or worse still, she had this level of command over a foreign language and wrote the piece herself.

The newer generation of all races understand this better. 

This thinking will die out in the wilderness, it has no place in Canaan!!!
