First of all, I don't think he's actually going to all that trouble to simply recycle what appears here and on other similar sites.

But let's say your description is valid. That still means he is choosing the words he wants for his reports. If you search the web for "Justin Bieber" "American Idol" and "orgasm" that's what you're going to find. If you search for "war" "disease" and "famine" that's what you're going to find.

So what is the basis for assigning "terrorist" higher emotional value than "Justin Bieber" other than personal bias?
