Theres a difference between embracing people of multiple cultures and disregarding your own for a mixed bag of everything. Most successful places have had a strong identity for immigrants to buy into, they arent timid afraid to protect their ways. America is a good example, its always been patriotic always had a strong sense of worth for people to buy into. Less so now and they appear to be sliding. When in Rome do as the Romans do wasnt said for nothing, it was buying into their ways. Immigrants buy into the host culture, it works.
Lose the identity, loss the will to defend or will to fight for it because whats the point if everythings the same? Then of course Rome had Germanic barbarians move across the borders seeking a better life from the empire, then a massive flood of them and boom....bye bye Rome. The Germanic people took on the Roman ways including the religions, it was stronger and better than their own even though they'd sacked Rome.
