I did get that you had problem with the concept of assimilation.
**If one gets ‘assimilated’ then yes, one loses the unique identity one has.
**
Assimilation means (in terms of culture): **Act of becoming like other people in another country or culture. **
Please go and read a dictionary and then come back to pick a bone with me.
If this simple concept is beyond your comprehension and intelligence level then I cannot help you.
Regardless of a society which includes people with different cultures at war or not, the society or the country is multicultural.
Where did you get the idea opposite to that? People don’t have to agree with each other’s cultures to have the country called multicultural.
P.S. It doesn’t matter if respect is due or not, that is purely up to your discretion I am fine as long as I am right and respectful.
