This is something like the Holocaust,
Ye’s saying that the condition of black people in America is something akin to the Holocaust. He’s being historical: he means the diaspora of people of African descent and how slavery and colonization have killed many people of African descent across the centuries. Further, the levels of crime, death, and murder that negatively impact African Americans has caused the loss of millions of African Americans' lives.
Although Holocaust analogies are always dicey, American slavery is probably a fair point of comparison, though not the contemporary black experience. Barack Obama also shares this view.
