Freedom and Liberty are two words often used in political conversations.

Liberty is essentially the right to complete control over oneself alone. The right to eat or drink any food or beverage, look anywhere, listen to anything, say anything do anything etc, so long as it is not touching on another person's space in any way.

The proper purpose of a government is to set rules about how people are allowed, or not allowed, to touch other peoples' space.  Liberty in one's own space is a property of nature. It cannot be given to anyone, since we already have it. It can only be restricted by force or deception. A person in a natural, healthy state has full liberty.

In a primitive society the responsibility for making sure the liberties of one individual do not interfere with the rights of another rests with each individual. When a person in a primitive society commits an objective crime, any other person present will try to stop the mistake. In a more urban society people demand an outside power, "the government" to "be" the morality.

Why is it wrong to kill? Because the government has made a law that says it is wrong.

Why is it wrong to smoke marijuana? Because the government has made a law saying so.

Why does a certain minority group need to be removed?

Why is it forbidden to wear a certain article of clothing?

Why do enemies of the state need to be eliminated? Because "the government" has decided it is necessary. Nature has been removed and replaced by the narrow short term interests of a ruling group.

There is an amazing qualitative difference in the morality of an urban (or "technological") person and a "primitive" one.

Both are subject to manipulation (by others more powerful), but when left alone, it is the primitive person who sees a world that he or she is responsible for maintaining. The urban person may see a government that they are responsible toward, or a set of laws, or some unnatural social structure, but they are blind to nature.

Primitive people may be dangerous when they perceive you as a threat, but urban people, the typical American, is dangerous if they perceive the chance to profit from you using laws that will justify their profit.

Liberty is no longer a relevant concept in those countries that hype it. It is just one more word that can be used by corrupt individuals familiar with the system to put themselves higher, and their neighbors lower.

Ironically, it is liberals (generally) who promote liberty and Conservatives who promote (lesser) freedom.

 Some conservatives seek to preserve things as they are, emphasizing stability and continuity, while others oppose modernism and seek a return to "the way things were". Wikipedia

Liberalism (from the Latin liberalis) is a political philosophy or worldview founded on the ideas of liberty and equality. Liberals espouse a wide array of views depending on their understanding of these principles, but generally they support ideas such as free and fair elections, civil rights, freedom of the press, freedom of religion, free trade, and a right to life, liberty, and property. Wikipedia

 Note that the equality liberals seek is one of liberty. The ideal of Liberalism is not that every person be identical, but that each person have the same liberties as any other.

Throughout history, conservatives have taken the language of liberalism and manipulated meanings to serve their ends. Remember that the founding fathers of America, every last one of them, was ultra liberal.
