So how many people have heard of Pizzagate, and how many of them ended up doing something deranged about it? (The article says no one was hurt, actually, but let's say someone was.) Meanwhile, how many people do deranged things because of beliefs that didn't come from the internet—say, they saw someone looking at them and just knew that person was evil, or they had some misfortune and blamed someone else and decided to get revenge? I submit that the type of person who believes a wacko theory and kills someone because of it is likely mentally ill, and might well have killed someone because of some other belief; the primary cause is the mental illness, while the specific belief and where it came from is not worth dwelling on.
