Sometimes the only way I learn or am forced to study something a little more closely is by arguing a certain position.
I want to learn about the Crusades.. i.e. get to the bottom of this quesiton so that I can answer the typical objection.. if there is an answer, that is..
So, those who remember your education, fill me in.
What was the occasion of the Crusades? How many Crusades were there? Were they justified? How many were really killed?
