answer: It is about the significance of race during an era of injustice and how one specific race can change the mind of others
Explanation: The author explains that the picture was paid for by a white person and expresses the hope for people to realize the fact that injustice is unacceptable. The fact the author stresses the fact that a person of the white or caucasian race wanted others to see the injustice of a minority race means that something like that doesn't happen often and its something to be excited about since it indicates change. The author expressing the pain they feel when a white audience makes unsettling faces at their friend means said minority isn't favored or seen as less by the in this case superior minority(whites). The fact that a white person paid to expose injustice to the general public means they are more inclined to listen and change their ways. This is why the author says the picture may help people see that injustice amongst others is wrong.
