What does the word 'civilized' mean to you? Can it be used to compare and contrast societies and cultures?

Do you believe that some cultures/societies are more 'civilized' than others? What is your definition of 'civilized' / what does it mean to be 'civilized'?

If you've studied history and/or anthropology then surely you've heard many uses of the term "savages" to describe groups of people that were considered to be less 'civilized' than whomever was writing that piece.
I was also just reading a book that described in detail some of the really horrible war crimes committed by both sides in the Sri Lankan civil war including but not limited to: raging mobs burning people alive, murder and rape of civilians, use of child soldiers, suicide bombers, etc. Please note that in no way am I considering the people of Sri Lanka as 'uncivilized', just using an example of what seems to be 'uncivilized' behavior.

An initial thought that I had was "huh, I'm glad I don't currently live somewhere where I could be burned alive based on my ethnicity/religion/beliefs by a rage fueled mob of people", but then the history of the western world came to mind - some of those exact same thing happened less than 100 years ago to many non-white groups of people in America, including some things even worse (read: human slavery). From here came a flood of other thoughts poking holes in whatever my initial definition of 'civilized' was. Plenty of things in present-day United States could be considered uncivilized. Yet one could make an argument that a more 'civilized' civilization might be one that allows many personal freedoms.

So, I want to ask all of you what you think of the concept of being 'civilized'. Is it a colonialistic-type term used to promote a higher sense of placement in the world that should be abolished. Does it have any merit in its use? If so, what do you think makes a civilized group of people and does one exist?
