It’s a very good question.

I believe that if one is/becomes a resident of a foreign country, one should get used to the cultures and customs, some might be very different from where you originally come from.

Proselytizing a certain “culture” over another can lead to pretty disastrous results.

Assimilation is a hell paved with good intentions.

Nevertheless, being polite, patient, respectful and open minded are virtues always welcomed.
