In a cruelty that was both useful and cynical, Islamic Sultans would forcefully implement a blood tax on the peoples of Byzantium. This “blood tax” found the Islamic Infidel seizing from the people of Byzantium their finest sons in order to take them back to Islamadom in order to turn these sons into the most elite special forces military units. These “Janissaries” were not allowed to marry and were considered personally owned by the Sultan. They were provided the very best of foods and drink. Eventually, they would be used as the shock troops against their former land from which they were kidnapped — Byzantium.
Today much the same is done by the Marxist conditioning as accomplished in our K-12 government schools and then our Universities all augmented and supported by our Churches. Only instead of having to kidnap the children Christian parents freely turn their children over to the enemy to be brainwashed. Like the Janissaries of old these children eventually turn on their parents and their former Christian lands in order to conquer them for the cause of Cultural Marxism.
