This is the most American, "I have never left my country and I don't really care about other cultures because mine's more important" thing I've ever heard. Enjoy your bubble, dude.
When I go overseas, places where English is rare, people also don't pronounce American cities or towns in a very English way --some sound foreign-- ask a Chinese to give you the name of any major city in your country/province/state. It's going to be quote different. Why should I feel any different?
