Ethnic Europeans don’t do that?
Unfortunately, that is not correct.
During the Balkan wars of the early 1990s, similar atrocities were carried out under the euphemism of “Ethnic Cleansing”. The perpetrators were all “Ethic Europeans”, and more often than not Catholic or Orthodox by religion.
Also, at a place called My Lai in a country called Vietnam, a group of American soldiers performed similar acts of savagery during a morning of rape, burning, murder and mayhem on a March morning in the year 1968.
