How long do you think an Arab would last in Han dominated China if he constantly criticized the Chinese for "Han supremacy" and called for an end to their way of life?
How long would a Han Chinese survive in Qatar behaving the same way?
Ironically, the openness of western society has led to its constant attack by disgruntled minorities. Who realized long ago that complaining loudly wins them resources and privileges.
I would classify this sort of thinking as "whig historiography." It's a popular meme, but there's no evidence that it's a good model of reality. https://en.wikipedia.org/wiki/Whig_history
Embracing "diversity is strength" feels good in an abstract sense, but it seems to fly in the face of evidence. The chaos and conflict brewing now are a direct result of this motto being played out over the last fifty years or so.
