Do you think people can be clannish toward others?

Lived in this state most of my life and my job took me all over the state. Would work for long periods of time in a town. Was an insurance adjuster that worked large losses after a hurricane, tornado, etc.

After being in a town for an extended period of time, you would draw conclusions about the town. Was it clean, was there pride of ownership, was it clannish, etc. This one particular town, will not name it, was very clannish. They did not take well to outsiders. They were very unfriendly. They usually knew everyone in town. Quick to say what their neighbors said about my company. Found them very difficult to compromise with over an issue. Very self-centered and judgemental. In my 25 years of doing this job, the most difficult group of people that I ever worked!

Do you know of a town, a family, an internet site, etc. that are very clannish? Why are people this way?
