MAHER: You're right, during the Middle Ages, I would say Christianity was the bigger problem.
Oh yeah, Bill, the Crusades, which were launched after 300 years of unanswered Mohammedan aggression.
Those Crusades, Bill? Learn some history.
Its more than just crusades. By the late Middle Ages, the Church was a very corrupt institution - half the Popes were either murdering their opposition (Borgias, anyone), or having children out of wedlock, or engaging in intense bribery -- (indulgences, anyone), that when there was push-back in the form of Martin Luther, there was equal and violent push back by the Church in the form of the Inquisition. It took hundreds of years for that to settle out, and it has settled out. The Pope we have today is such a holy man and would have been totally out of place in the Middle Ages.
It is you that should learn some history. I don’t think Maher was referring to the Crusades but to the mass slaughter between Catholics and Protestants not to mention the torture chambers operated by the church. Christians were killing Christians. Heretics and women were being burned alive in the name of Christ. People who thought the earth was round were killed! Modern Christians must disassociate themselves from the crimes of the Christians of the Middle Ages.
