The words America and Americans to describe this country/colony have been used a long time.For example, Nathaneal Greene, a general in the American Revolution, used the term "America" referring to the United Colonies in a letter to a friend. Again, in a letter by Greene to John Adams, he used the term "American politics". Both the British and rebels used the terms America and Americans. So, no, their usage does not reflect any extreme pride or jingoism as they have a long history of usage.
