There are a couple of great posts at Stuff White People Do about To Kill A Mockingbird that get into aesthetics, culture, canon, and social justice. Be sure to read the comments because that's where the real action is.

It's one of those rare discussions about an incendiary topic (especially down South where I'm from) where there is disagreement without denial, dismissal, and delusion.
