Controversy rages in the United States between those who wish to restrict government involvement with religious institutions and remove religious references from government institutions and property, and those who wish to loosen such prohibitions. Advocates for stronger separation of church and state, such as already exists in France with the practice of laïcité, emphasize the plurality of faiths and non-faiths in the country, and what they see as broad guarantees of the federal Constitution. Their opponents emphasize what they see as the largely Christian heritage and history of the nation (often citing the references to "Nature's God" and the "Creator" of men in the Declaration of Independence and the dating of the Constitution with the phrase "in the Year of our Lord"). While broad defenses of religious freedom were historically understood as ideologically liberal, in has been opined that in the 21st century they are understood as ideologically conservative. Some more socially conservative Christian sects, such as the Christian Reconstructionist movement, oppose the concept of a "wall of separation" and prefer a closer relationship between church and state.
