"The governor could be excused for not knowing that what she held in her hand was a translation, but not for mixing state and religion. But here we'll focus on the former."

Despite the fact that said governor lacked some common sense, she did know her Constitution and Amendments.
The phrase "separation of church and state" are not in the First Amendment, or the entire Constitution for that matter. Nor separation of religion and state. Rather, the First Amendment reads: "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances."

While I don't agree with the governer's stupidity on foreign languages, I do believe that you should research what you send out to make certain it's done properly.
