There has always been multiculturalism, even hundreds of years ago.

One example was Córdoba, where Muslims, Jews, and Christians lived together. They even had different laws, because the Muslims had what they called "dhimmi" status, which meant that different groups had their own jurisdiction granted by the Muslim rulers.

This ended because of many factors, one of them being the collapse of the Caliphate due to internal strife. So I grant that it is difficult, but not impossible.

Our descendants will see if this form of living together can be sustainably established in the future.
