The book, "Blankets," includes graphic images of masturbation, sexual encounters, and "a child being raped," according to Tim Reiland, the father of two children who attend Owasso Public Schools.
The Twitter account Libs of TikTok tweeted some of the graphic contents of the book.
"There was children with their penises showing that were urinating in each others' faces. There was scenes, and this is graphic, images of ejaculation. There are scenes of teen sex. There are also scenes of a child, a child being raped in the book, and all in graphic depiction," Reiland told NewsChannel 8.
Reiland said the school initially responded by pulling the book for review.
"I was very happy with that. I thanked them. I sent emails thanking them," he said.
But when Owasso school board members voted against a new policy to restrict “pornographic content” from the district's libraries, Reiland confronted a board member in the school parking lot. According to witnesses, the exchange was not violent but did include a few choice words.
A few days later, Reiland received a letter from Owasso Superintendent Margaret Coates effectively banning him from school property for six months.
"You are hereby directed to leave the Owasso Public Schools and all of its grounds (including sports venues) and not return," the letter said.
Reiland said he can't even pick his children up from school "without written permission from Margaret Coates."
