"I detest racialism, because I regard it as a barbaric thing, whether it comes from a black man or a white man"

In this quote, Nelson Mandela expresses his strong disapproval of bigotry, or the belief that particular races transcend or inferior to others, which he thinks about a barbaric and savage mindset despite whether it is revealed by a person of color or a white person. Mandela recognizes the hazardous and divisive nature of such beliefs and advocates for greater unity and equality among all people.
