.What do you think accounts for the enormous popularity of "black minstrels" with white audience's

Explanation:

Minstrels were created by a Canadian named Rice. Like movies, minstrel shows were created based upon audience tastes and values. The first step for superior group to control another group is to objectify them. Minstrel shows portrayed African Americans as simple minded, happy, musical, and lazy people who are happy to be a slave. White people wanted justify slavery. They wanted to see that black people could benefit from the slavery. They liked to think that their slaves were minstrels rather than normal human being like themselves.  In addition, people love watching idiots and they want to believe that they are smarter than others.
