The minority always feels themselves marginalized as to some extent the majority of people though might not segregate but would always prefer one of their kind.
The best, tried and tested solution for it is love. Do love and breed so that there would be no more pure blood or pure color.
no people always complain, and insult others as whatever (racist etc.)
till they get what they want, and there are things humans never get enough of (money, power) and therefore people will always complain a society that listens always to complains destroyes itself
