That will not be a happy future for anybody as it comes to pass. There is no "elsewhere" for Whites to go. And no amount of goodwill and appeasement will protect Whites from predation at the hands of Blacks and other non-White ethnic groups. Other more effective measures will be required.
The Middle Eastern, Chinese, Korean, Indian (dot, not feather) and Hispanic groups will join in the looting of Whites. They will not, however be opening up anything to Blacks, or each other. It will be a very complex maze of shifting alliances and betrayals all around.
The folks who prevail will be the ones who keep a wary eye on their neighbors and stick with their own kind. It will generally work better to deal with people truthfully and honestly - while bearing in mind that others may not always play along with those rules.
Separated ethnic communities will be an obvious solution and it will work. The "Cosmic people" who believe otherwise are being conned. They will end up as lunch for somebody.
Philadelphia started out before the American Revolution, and adopted the Christian-values motto: "The City of Brotherly Love." For generations it prospered that way, with a patchwork of easily-identified ethnic neighborhoods, each with its own church that spoke the Old Language as well as English, with its own ethnic restaurants and groceries carrying the favored ethnic foods. Everyone else could visit the restaurants, grocers, street music fairs and church-sponsored ethnic festivals, and everyone could participate in the all-city American festivals such as the 4th of July parade, Thanksgiving Parade, etc.
Even in the late 1980s, with its patchwork of voluntarily segregated ethnic enclaves, Philly was among the FBI's list of the top ten safest American big cities.
But eventually, accelerating from the Clinton era onward, cultural marxism began encroaching—featuring denunciations of whites, straights, Christians and even the Boy Scouts, breaking that organic system of "getting along" into smithereens.
And now look. 500 murders a year.
