United States has 1 common language, you realize sometimes we move 200km here and we don't understand each other? But I agree, in broad terms we are more similar than not (we all agree on the same things on human rights, individualism, separation of State vs Religion. Check: https://en.wikipedia.org/wiki/Hofstede's_cultural_dimensions_theory https://en.wikipedia.org/wiki/Hofstede's_cultural_dimensions...). It's just that in less broad terms - say quite kids - we are very, very, different. It's a matter of understanding which layer of culture you are referring to and avoid broad simplifications.
