So every country has its own cultural diversity... if you travel to another country you have to adapt because every country is different in cultural diversity. Ofcurse people who come to your country should adapt to your country's cultural diversity, but they don't need to learn it unless they want to stay in your country permanently, this apples the other way around as well.
If you have a population of 1milion people those milion are not going to adapt to 1 person but 1 person will adapt those 1milion. So I partially agree.
