Politically "active material" is, for some reason, the only branch of knowledge that we all seem to agree can't be expressed in words. I can tell you everything known about the effects of... caffeine on general health: all I have to do is start talking, and then not stop until I've said every well-supported, relevant fact. There's absolutely no fundamental reason why I can't put the profile of an undocumented hard-working fruit picker in the same broadcast as a report on a brutal drug-related homicide believed to have involved people here illegally. There are many political reasons why I wouldn't do that, most of them related to the motivations that drove me to do character profiles (a dangerous combination of emotional credibility and statistical weakness) in the first place, instead of having calm talks about the large averages that we use to illuminate every field of truth that's devoid of strong ulterior motives.
