This exchange in the video that you'll see below is instructive. It's between far-left media personality John Jay and Margolis:
JAY: "One of the reasons the word 'terrorist' is often or almost always associated with Hamas is 'cause certainly they have used terrorist tactics. Hamas has taken credit for blowing up civilians in Israel which is a terrorist tactic, so doesn't it deserve some of that label?"
MARGOLIS: "Well, uhh.. I ..I..uhh..shudder at the use of the word terrorism because it is so.. it's a propaganda rather than descriptive term.."
