Can There Be World Citizenship?

World Citizenship is great but not realistic in my eyes. I think that worldwide it’s just not as possible as people make it out to seem to be. First off we alienate people from other countries and when we think worldwide no one is an alien if it’s about world citizenship I would think. But not just that, there’s too many people in the world with beliefs, morals, opinions, etc. that conflict with each other that makes it not possible for world citizenship to be even close to realistic because some people just can’t accept others the way we should all be accepted. Many people are not responsible and aren't good citizens in their own countries. Doing that seems to be a challenge enough so what would make worldwide citizenship any easier? I think that it is a dream for the future that maybe someday it'll come through and start to see more results of it but at this point in time in our history I just don’t see it. Many people are very judging in this world some of other ethnics, or even other countries. When not everyone can fully accept people of different race, religion, beliefs, other cultures, etc. in our country today, if you could imagine that being blown up into world wide it would be only worse because it’s not just our country we are thinking about. It is the whole world that is judging each other when we are supposed to have this idea that we are brothers and sisters from this world that should all be citizens with each other and for the world to accept each other for this plan to work and that doesn’t work out.
