People dislike what they see as thier cultural identifiers being replaced with those of a different culture, regardless of what might make political or economic common sense, be it through interplay, assimilation or cultural growth, development or trading, if it is sudden and appears to have no net positive gain. The Roman Empire spread through Europe, Middle East and North Africa as it generally led to improvements in the quality of life for people (gross generalisation i know). You try telling a Catalonian that they are Spanish, or telling me that I am English. Here in Wales one way we have dealt with this through entrenching in Law the protection of a number of cultural identifiers, with the most visible being the Welsh language. Seems to me a large amount of this "globalization is bad" is just a way of saying "USA out!" or "Death to the West!" and suchlike... some irony here seeing as many nations around the world that appear to be anti globalization have fallen under the yoke of some truly harmful imperial states and come out the other side with thier national identities more or less intact (heck, centuries of oppression under English rule in the middle ages has created the Welsh national identity), and are also all too willing to accept £, $ and € for tourism or oil. Will be interesting to see if the emerging powers of India and China "influence" western culture (in ways other than offering us tasty take away food for reasonable prices), should they go on to surpass the western world as some have predicted.
