Interesting how the “celebrate diversity” crowd is so uninterested in understanding & respecting actual diversity.
Few things are clearer to anyone with analytic ability, than that forcing incongruous peoples to accept each other in once culturally identifying settings, such as schools, established neighborhoods or even broader communities, can only tend to decrease the actual "diversity." No, it will not morph one type into another; but it will surely decrease the ability to "celebrate" your actual diversity from others in the newly diversified neighborhood. (The examples in States over-run by illegal immigrants, should come to mind. But the expected phenomenon has general applicability, and is not over-looked by the social engineers, who wish to dismantle America.)
