Untouched civilization

I posted a comment on the following site - http://goldwaterlibrary.typepad.com/rgl/2008/05/rare-uncontacte.html. The thought of not engaging a civilization whether modern or not seems atrocious to me. To say it is better for people to remain hunters/gatherers and not develop and engage as a socially connected human race is ignorant and demonstrates our fear of differing societies and internal desire to remain superior over other races and societies. I think we see this same basic thinking when we look at Christians, Jews, Muslims or even communism and democracy.
