Christianity is the perfect example of 'Conquest by Religion'. Those that invented Christianity were physically weak,they knew they couldn't conquer the Pagan European Barbarian by Force. So they conquered the minds of a few Barbarians, then it spread like wildfire throughout Europe, as these few barbarians rampaged throughout Europe, spreading Christianity by the Sword. "Follow our religion, or we'll cut your fucking head off", said the christian. Hundreds of thousands of my ancestors were wiped out because of this alien desert religion.
