Have you seen what passes for "online abuse" right now? The fact that Fisk earnestly uses the phrase "methodological terrorism" suggests that she is not to be trusted with negative connotations.

Everyone agrees "abuse" (connotation: wife beating) is bad, so people like Fisk just redefine "abuse" to mean "being blunt online", and people who aren't inoculated against semantic overloading techniques fall for it.
