Nah. You cannot say, do you people still throw spears at each other to Australian Aborigines and not be a casual racist.
You cannot say, you survived not getting eaten to a student hiking in Papua New Guinea and not be a casual racist.

and How many Turks did your dad slaughter?
Culturally, his people are just as weird as everyone else and everyone has ancestors who were monsters.
