The guy arrested for trashing a Kim Kardashian book display wasn't motivated by Kardashian hatred … he just thought her book was too pornographic and accessible to kids in the store.
Carl Puia tells us saw a mother yank away a copy of "Selfish" from her young boy in the Barnes & Noble. He says it was being displayed on an eye level shelf, not far from the children's section.
Puia claims he asked an employee to move the display to higher shelves, but 3 days later he returned and it was in the same spot. That's when he decided to go back and destroy the books with red liquid.
The 74-year-old says he's no holy roller, he just believes kids shouldn't be exposed to smut … regardless of what celeb is behind it. Puia says he only turned himself in because he got a call from police saying a warrant was out for his arrest.
