History is brutal. If the native group's genetics don't get eradicated. The alternative can be just as grim. Often, the winners genetics in a person can be the result of wide-spread rape of the native population after the native males were slaughtered. Today's evils were ancient history's most peaceful methods for resolution. Colonialism and Slavery were merciful. On some occasions, explicit class/caste systems allowed the losers to continue living as the underclass. Mass exile to barren lands came with famine & drought, but at least a minority surivived and maintained self-governance. The world has civilizationally come a long way from then, thank god we did.
