Look, I'm a visibly nonwhite immigrant. I am proud to be a naturalized American and have renounced all legal ties to the country of my birth. I think dual citizenship is at best weird, and I honestly don't understand how one squares that against the oath of allegiance. I believe the onus is upon the immigrant to assimilate, and that America is a rare place where that is in fact possible. I have no desire to recreate the country of my birth in America, especially not in a segregated ethnic enclave.
I would like to live in a colorblind America and, though it may sound implausible to you, I believe the American right has the better claim to that future than the left. I do not empathize more with potential immigrants from my ethnic background than I do with my fellow Americans, and I quite dislike it when those from the left automatically assume the former, because it means they are treating me as being fundamentally different than any other American. And I think this mindset is table stakes for any immigrant to any nation.
Much of the West has seen levels of immigration over the past few decades beyond the capacity of the native population to absorb in a way that results in assimilation. It has increasingly been from cultures that are substantially different, further hampering that effort. It's disconcerting to see that any efforts to pump the brakes even a little bit immediately results in accusations of racism or fascism.
[0]: I don't want to split hairs over 18th-century Deism. All of that was contained within the Christian cultural framework, anyway.
