Well, you're wrong. It's insufficiently descriptive. Anybody who kills another using an explosive commits a homicide bombing. "Suicide bombing" describes a subclass of homicide bombings, in which the bomber deliberately kills himself as part of his plan. Fox's insistence on this silly term led to absurdities like last weekend where the network reported that Iran had trained a cadre of 40,000 "homicide bombers" to attack American interests in the event of military action against them.
I've long held that the honesty and suitability of a term can be judged by imagining how accurately somebody who had never heard it before would guess its meaning on hearing it for the first time. "Affirmative action" fails the test. So does "welfare". "Pro-choice" and "pro-life" both. And so does "homicide bomber." Fox doesn't (and would't) describe people like Timothy McVeigh and Theodore Kaczynski as "homicide bombers", but somebody who had never heard the term before would never guess it.
Homicide implies taking someone else's life. Which is what this is all about. I could argue the evil vermin that indiscrminately slaughter innocents aren't worth enough to count as suicides.
I'm not wrong.
