This is not something that can be stated about all Americans, though. But a lot of Americans have very strong religious views. They might not know much about other religions because they grew up in a place where almost everyone else they knew shared their religious beliefs. This could be a problem when they go to nations where the main religion is not theirs.

If you want to avoid acting like a tourist when traveling (and just be a decent person), make sure you embrace and understand other people's beliefs.
