Rarely does one find much extensive diversity in any given town in America. Most of the diversity seems to come from the large cities, where people of other nationalities, races, cultures, and religions seem to collect. The U.S. is so vast and pretty isolated except for the southern Mexican bottom and the northern Canadian top, which still only provides for two major diversities. However, even though Great Britain is quite isolated (as it is an island), it is still so close to all the different parts of Europe, Africa, and Asia.
True, Allegheny college and most small or little-known cities in America offer some diversity, what with individuals' lifestyles, religious beliefs, cultures and backgrounds but it doesn't seem to offer the same diversity that even this small town of Lancaster, England offers. Diversity is the norm here -- walking to class I will usually hear several conversations each spoken in a different language. There are social clubs and groups dedicated to a vast array of different hobbies, talents, religious beliefs, cultural activities, etc. I have met people at Lancaster University from all over the world, from California to Australia, that have offered me an insight to diversity.
Coming from a small town in the U.S., I don't get to see much diversity. Sure, I see many races - caucasian, Asian, African American, etc. But simply race does not account for diversity. America is known as "the melting pot", so while we may all be different races, we are all still Americans. However, over here, you will meet people that live in Asia, the Middle East, or Eastern Europe that have come here to study and that bring with them their culture, beliefs, and lifestyles. It is not all melted into one nation with differences amongst it, but it is many different nations that come together to share with eachother while gaining a good education.
Diversity to me is the ability to have many differences (other than the color of your skin) among others that you exist with while maintaining your identity, and to accept everyone's differences in a large mutual relationship of learning and understanding and enjoying.
