The United States is a glorious democratic nation that supports everyone's irrefutable right to worship whatever god or gods they wish. The government guarantees that right and it shouldn't be discriminated against by other people or in the laws we make. I am a Lutheran (ELCA) and I am proud to live in a society that accepts people who go by other religions and cultures as well. It makes our society more interesting and effective with more ideas coming from different backgrounds. By whatever name you call God you should be welcomed into your chosen community in the United States.
A country that has the right to practice a religion should not be considered a Christian nation. Moreover, it should not be labeled as such. Putting a religious label on a country is an indirect paradox for a right in said country's constitution.
"..The First Amendment of the United States Constitution protects the right to freedom of religion.."
"Two clauses in the First Amendment guarantee freedom of religion. The establishment clause prohibits the government from passing legislation to establish an official religion or preferring one religion over another. It enforces the "separation of church and state." Some governmental activity related to religion has been declared constitutional by the Supreme Court. For example, providing bus transportation for parochial school students and the enforcement of "blue laws" is not prohibited. The free exercise clause prohibits the government, in most instances, from interfering with a person's practice of their religion."
