When Dr. Martin Luther King Jr. realized that not all blacks were united around the struggle for civil rights during the '60s, he lashed out. "Negroes are human, not superhuman," King said in The Sword that Heals. "Like all people, they have differing personalities, diverse financial interests, and varied aspirations. There are Negroes who will never fight for freedom. There are Negroes who will seek profit for themselves alone from the struggle. There are even some Negroes who will cooperate with their oppressors. These facts should distress no one. Every minority and every people has its share of opportunists, profiteers, free-loaders and escapists."
