"Homicide bomber": This term was created because the term "suicide bomber" apparently created too much sympathy for the perpetrator. But most educated adults should recognize that there is no direct relationship between the righteousness of a cause and how suicidal its adherents are. For example, the Kamikazes of WWII fought and died on behalf of a genocidal regime. "Suicide bomber" is a more descriptive term than "homicide bomber". Most terrorists who set off bombs do so with the intent of committing homicide, a fraction of these terrorists deliberately kill themselves with the explosions that they detonate.
"White slavery": Slavery is a crime in this country. News anchors usually do not go out of their way to identify the race of a victim in a story. You don't hear about "Hispanic murder" or "Asian rape". The crime is heinous regardless of the race of the victim.
