Why are people defending having pornographic books available in children's libraries?

Seriously A leftist anchor at MSNBC stated that a book "All boys aren't blue" Which depicts graphically, and adult male having sex with a minor male child. Her response was "What if some child felt seen by this" If that child felt seen by a book that depicts graphic child abuse and child rape, That child needs psychological help NOW and the parents investigated, because no child has thoughts like that, unless they have been abused.
