To Kill a Mockingbird was written in 1960 and the movie in 1962 and you’re talking about institutionalized racism. Have you ever considered the possibility that treating someone differently based on the colour of their skin and saying “it’s okay to commit a crime because someone was racist to your group of people generations ago” is in and of itself racist? You’re treating someone differently because of their race. And to bring up a book written before Black Suffrage and claiming that that is a clear cut demonstration of society today is not only disingenuous to your own argument but it’s insulting to anyone who has ever made a difference in promoting the rights of those seeking equality.
