What nonsensical subjectivism..
I didn't say that serial killers outside the Anglo nations are nonexistent, I said that they are far rarer. Pretoria, I might add, is an essentially Anglo culture (I am also including Australia, which has plenty of serial killers you neglected to note).
I was well-aware of Pedro Lopez and was actually going to mention earlier that there seems to be a (widely noted) upswing of the serial killer phenomenon in Latin America in recent years. In fact, there is some debate there whether that is 'home-grown' or an import of U.S. sensibilities (or whatever one might call it).
I counted 58 killers on the Wikipedia list provided earlier. By all means provide the names of 350 Chinese & Indian serial killers, 350 non-Anglo European killers, 200 Latin American killers, 200 African killers, and 150 non-Sino/Indic Asian killers that would demonstrate the comparable rates.
And of course I'm talking about serial killers in the sense that the term is used in America, not in the sense of someone who mass murders in war or cases of terrorism or through some official capacity.
You still miss the point. Alas.
