Can There Be World Citizenship?

It is more than possible for there to be world citizenship, the problem is people finding the will to act upon it. When we watched the documentary "Ask an Iraqi", it showed how many people in the United States aren't very accepting of others who aren't originally from here. We victimize others and make it unpleasant for those who are here for a better life not only for themselves but for possibly further generations in their family.  I feel that this currently affects my generation because we see our elders responding to others in this manner and what we observe is what we pick up as we get older which leads to the conclusion that Raina Kelley came to in her article, "Generation Me." We're viewed as selfish and narcissists but a lot has to do with what we have seen and are currently seeing as we get older and we see the rejection of other human beings and in result, we carry that on.
