Oddly enough, while I don’t agree with picking an official religion for America, I don’t have a problem with our adopting English as our official language. Even if America declares itself a Christian nation people will force us to agonize over which “brand” of Christianity America will adopt. If you need to be convinced that religion should be separate from government read about the period in England when Henry VIII decided to make the king (himself) the head of the church in England. It wasn’t pretty. And although England has made its peace with having a state religion, this tradition is long and well-established.
English has been the language of the United States since our earliest days. Although the French and the Spanish both controlled areas of the New World, those traditions did not win the day. Through successive waves of immigration English has dominated. The Irish came, but we do not speak Gaelic; Italians came, we do not speak Italian; Chinese came, but we do not speak Chinese; and on and on. Still I believe we will always have to help new residents learn English and it would not hurt Americans to become proficient in more than one language.
