Nothing unites a nation like a common language. What is she afraid of?
Lie.
A friend of mine went into the Army and some of the manuals were Spanish/English. She worked with explosives sometimes. Since Spanish was her first language, that helped her do her job. Having multi lingual manuals, ballots, forms etc excludes nobody and allows all who want to engage in the processes that do truly unite us.
Utter bullshit.
There's no motivation to learn English if all government functions are provided in various languages. We are a fractured society, and one of the chief reasons is we are separated by different languages here in our own country.
A common language is key, otherwise people tend to stay in their own group.
