Liberals believe they’re above the idea of race and tribe so they don’t see invaders moving in as a problem. However, they not only acknowledge but encourage shit skin races and tribes. Liberals are people with zero self respect.
"Ethnicity" has become a de facto euphemism for "race" in contexts where "race" is a no-no word. And because we can't talk openly about race, a lot of people don't get that there are subdivisions within blacks as there are subdivisions within whites (Latins, Slavs, Nordics, etc.).
