Additionally, there are may be atheist and agnostics in your audience. The terms "atheist" (lack of belief in any gods) and "agnostic" (belief in the unknowability of the existence of gods), though specifically contrary to theistic (e.g. Christian, Jewish, and Muslim) religious teachings, do not by definition mean the opposite of "religious. " There are religions (including Buddhism and Taoism) that classify some of their followers as agnostic, atheistic, or nontheistic. The true opposite of "religious" is "irreligious. "
Since the First Amendment to the U.S. Constitution guarantees the separation of church and state, the U.S. has no dominant state religion. People with different beliefs are free to practice their religion in the U.S. or to practice no religion.
