Chicago Public Schools Protect Students from Dangers of Reading

After the Chicago Public Schools wisely called for schools to round up the graphic novel Persepolis from its libraries and classrooms for presumed future burning, it was immediately criticized by the Chicago Teachers Union and Liberal Mouthpiece Kristine Mayle who said, "We are surprised ‘Persepolis: A Story of Childhood’ would be banned by the Chicago Public School (CPS) system.  The only place we’ve heard of this book being banned is in Iran. We understand why the district would be afraid of a book like this-- at a time when they are closing schools--because it’s about questioning authority, class structures, racism and gender issues. There’s even a part in the book where they are talking about blocking access to education. So we can see why the school district would be alarmed about students learning about these principles."

I'm sorry, but looking in the page above, I just don't see any similarities to CPS at all.
