Why would a Korean be offended if a Chinese person dress like a war-torn Korean?  Why would a Jewish person be offended by a German dressing like a stereotypical Jew?  Why would a Native American be offended by a white American mocking their misfortune at the hands of their oppressor?  Why would a black person, with African roots, whose ancestors were enslaved and  killed feel good about being mocked in what some called a cinematic work of art: The Birth of a Nation.   A movie that featured white actors in black-face, who were portrayed as murderers and heathens before the Klan saved the day.   The reason, in most instances, is that most of us are not informed or just ignorant.  So, why don't we make this personal...Think of the worst thing someone could do to a family member, and then imagine them showing up next Halloween at your doorstep wearing your family members likeness.
