Looking over at the headlines on pjmedia (na I’m not interested enough to actually read the articles) it looks like they’re blaming the shooting on:
a) evil and
b) moral relativism

A is just stupid. Shooting kids is evil, but that’s the event not the cause. It’s a bit like saying “no no no they didn’t die because of guns, they died because they were full of little holes”

B is just another example of using a tragedy to sell your favorite snake oil, like the guy who said it’s “lack of God in the classroom”
