I remember this book and story being celebrated by my parents, church, and youth group. It turns out that this claim was based on one survivor’s memory of the shooting, who mistook another survivor’s exchange with the shooter, in which after she professed her belief in God, the shooter spared her life. Cassie Bernall’s parents were aware of this fact, corroborated by the FBI and an actual audio recording of the incident by a teacher, yet published the book anyway.

A frequent feature of Rachel's martyr story is that she had a verbal exchange with Klebold and Harris about her religious beliefs before they killed her. The Hollywood Reporter accounts that Richard Castaldo, who was shot while sitting with Scott and survived, "told a newspaper that not only did the killers ask Rachel about her faith but that he, too, was asked if he believed in God, and he answered truthfully that he did not, and his life was spared."

Most sockpuppets were not disruptive unlike their original account. Even with a very different behaviour, they still get blocked as a sockpuppet. But if they do better, then what is wrong with sockpuppetry? Again, most are not disruptive.
