Arab Christian, there were a number of Christian terrorists at the time, most prominent the Popular Front for the Liberation of Palestine, still around though now Muslim. Marxist organizations, as are all (?-am I missing anyone) of the Arab terrorist groups. Big on hijacking and airport attacks. Arab terrorist would be better than jihadist in describing Sirhan, same motivation, but Christians have gotten out of the business, so I’m not sure there’s much harm. And as I noted, it was Arafat killing American diplomats to free him.
“Sirhan Sirhan was a Muslim?”
Nope, although today I heard the CBS News mistakenly say that he was. Sirhan was an Arab Christian. A coworker of mine worked alongside him one summer at Santa Anita Racetrack, shoveling out stalls.
