"Crusaders may have been Christian"

MAY have been Christian? The Crusaders weren't Jewish. They weren't atheists. They weren't Buddhist. They weren't Hindu. They weren't polytheists. In the Middle Ages, being a member of any of those groups was grounds for a public barbeque, with the offender as the main attraction, assuming Middle Ages religious and political leaders knew what a Buddhist or a Hindu was.
The Crusaders were definitely Christian.
The Popes sanctioned the Crusades. The Crusaders' shirts had nice big red crosses on their chests, and no, it wasn't to identify them as medical workers. The crosses did give Muslim archers nice aiming points, -- crosshairs, so to speak -- but that was an adverse side effect.
How about reading the very first comment by old cool, reading my comment in context, then getting back to me?
