Why is Liberty so Popular?

A group of criminals -- that is, people who broke the law -- in colonial American were called the 'Sons of Liberty.' One slogan of the French Revolution was 'Liberty, Equality, Fraternity!' Today, I drove passed Liberty Avenue in Whitesboro. President Bush makes constant reference to Liberty's twin: Freedom.

Why are Liberty and Freedom so popular while Equality and Fraternity are either ignored or scorned as Socialism, Communism, unAmerican, etc.?

Here's what I think: Liberty is personal. It relates to "you." Equality and Fraternity are social; these concepts involve "other" people. Liberty represents selfishness, so it is widely popular. Equality and Fraternity represent sacrifice, so it's better to ignore them.
