When my son was in the 3rd grade, he was having trouble catching on to reading. I bought him a book called "what would Jesus do?" He was so proud of that book, and he tried reading it more than any other book from school or home. This class had a free day when you could bring a book from home to read in class during free time, (not out loud, this was personal free time).
Well, he chose to take that book. When he got home he threw it across the room and said, "I hate that book, and I hate school!" Apparently the teacher had taken the book away from him and lectured him in class about how it was against the rules to bring such material to school, and threatened him with suspension! That was his first week at that school in a new state, so he was having to adjust to a lot. When the biotch teacher called to chew me out, I went off on her. He has hated school ever since. They even called a meeting at the school which included the teachers, the principal and a psychologist to discuss the evils I had allowed! I told them they were all full off shit, and if they ever did anything to embarass my 8 year old again, they would really regret it more than inviting me to thier stupid meeting.
So a book that promotes violence and self mutilation, in school libraries? Let me find it, I will start the SHTF club.
