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.
Might be time to look at a Calender and join the real world. Maher's right on this issue. TODAY we are dealing with a radical Muslim problem. That's on the table today. Today. Today. Today. IN OUR TIME.
It's like that weird thing some did with hating Germans and "japs' decades after the War... The evil people in charge during World War II are dead. They aren't leaders of those countries any more... The ideas the pushed their hate is not in vogue.
And your position about the Christian Church - actions fom hundreds of years ago impacting today is even ... what's the word... odder?
