It will stay with us ALWAYS — get used to it. It is part of human nature.
We give it a nice veneer by calling it ‘racial diversity’ or ‘multiculturalism’.
It will only get worse.
No it is NOT part of human nature.
What IS part of human nature through all recorded history is the tendency of societies, large and small, to produce predators; that implies prey. For 99% of history societies dealt with the problem swiftly, effectively and rationally by killing the predators, who are always vastly outnumbered. Problem solved.
Human nature, the essence of humanity, is creativity. Survival through work, cooperation, inventiveness and slow progress to a better, safer and healthier society. The predators ever present notwithstanding.
Then humanity evolved into a "better" higher level where the predators were more and more tolerated until they were granted the special privilege of remaining alive no matter how ruthless, barbaric or disruptive their behavior.
This was seen as a virtuous quality; cultural suicide.
This new pardigm was viewed as progress.
There is nothing civilized about acccepting rule by the criminal classes as "civilized." Nor is it part of "human nature." Not ever; not now.
