such things happend all the time before.
When the nigger zulus overrun Afrikaan camps (the mostly Dutch, and sometimes french protestant and germans) they killed everyone including infants. raped the foids too.
and the most cmmon in history was when gooks like huns, mongols, turkics etc. mass rape and genocide whites.
huns did it to Gothics (a Eastern Germanic people) in Ukraine (Ukraine was Germanic and after that genocide, became Slavic, as the Slavs who were originally a fringe people, became to multiply like rabbits and occupied the empty land after the genocide)
then in 1200s the Vikings which were also Germanics, had built kingdoms for hundreds of years in Ukraine and Rus, collevtively called Kievan Rus, ruled over Slavs. Then the mongols came and destroyed almost ALL cities. How many Nordic giga stacies they gang raped, mutilated, tortured?
Western china used to have Tocharians, a people related to Germanics, Italics, Celtics, but got genocided, first by the Xiongnu, then the survivors got exterminated later by the Mongols hundreds of years later in Tanguts (some top Tangut loyalties had Tocharian surnames incidating their origins) and in Central Asia where they wiped off every single city and town there.
China uses to have redheads, as proved by the discovery of the mummies who were totally white and had red hair.
