Ethnic cleansing is much more straightforward than you are making it out to be. How is it that these people can be targeted with discrimination or verbal abuse hurled from across the street, but those same racists armed with murderous intentions would be unable to find them? That's just silly. Humans have been doing this longer than we've been writing down our own history. "Industrial" genocides like the Holocaust are the exception, not the rule.
