re: #50 pre-Boomer Marine brat
I’ve read that the saying came from Arnuad-Amalric (under Pope Innocent II) who commanded a Crusader army in 1209. Arnuad-amalric murdered Frenchmen while pursuing alleged heretics in Beziers…When Crusaders asked Arnuad-Amalric who they should kill, Arnuad-Amalric responded: “Kill them all! G-d will recognize his own.”
