Yes, yes, perception and all that but the word does have a stock definition: Someone who uses violence either (or both) physical or psychological violence against non-military trgets in order to achieve specific agendas.
Rabin under this definition? Not at all. Ironically, it is actual Jewish terrorists that are responsible for his death (one actual killer, Kahanist, many supporters and accomplices) so it is a pretty strange comment.
The only people who make such claims, that the man who orchestrated Oslo, and was directly responsible for the creation of the PA, are people such as Kahanists and the other end of the spectrum, all or nothing Leftists like the good and dead Israel Shahak as the West calls him.
Shahak accused Rabin of all sorts of lies and garbage. So, if you think Rabin is a terrorist you are probably a Kahanist or a person who claims the Talmud demands that Jews spit on non-Jews,etc like the dead nut job Shaha.
