Once upon a time, America had a single overriding ideology... Liberty, the idea that people should make decisions for themselves, and reap the benefits or suffer the consequences of their own actions. The Constitution guarantees liberty, and the Pledge of Allegiance aspires to “liberty for all.” Thomas Jefferson & James Madison enshrined the concept of liberty during our country's founding, and every single American president since just assumed that America was a nation of liberty. The fact is, America is the only Liberty nation in the world because we make liberty the primary objective, all other countries being some form of collectivism.

An attorney must use the word "liberty" as it will be enforced in a court of law. From Black's Law Dictionary:
Liberty: Freedom from arbitrary or undue external restraint, esp. by a government.
Natural liberty: The power to act as one wishes, without any restraint or control, unless by nature.
Personal liberty: One's freedom to do as one pleases, limited only by the government's right to regulate the public health, safety, and welfare.

Often The Left or The Right will claim there is some mystical power that supersedes or modifies what "liberty" means but then those folks end up in court where Black's Law Dictionary prevails.
