Freedom sort of...it's a word just tossed out there all the time. It's sort of a selling point, like you mentioned. It's come to the point to where it has lost it's meaning. If a group of people (GLBT community, for instance) in your country aren't free, then saying "the land of the free" is a lie, in my opinion.
Anyway. I think freedom is more of a feeling...though it's a temporary one. We're all slave to something. Freedom is just a nice word, imo.
