They probably don’t want people to find out how many protestants were killed by the catholic crusaders on their way to Jerusalem.
Protestantism began in the 1500s. The Crusades ended around 1291. There weren’t any Protestants when the Crusades took place. So, there weren’t any Protestants killed by Catholic Crusaders on their way to Jerusalem or anywhere else.
Now this is being silly.
There are lots of FReepers who could tell you all about that.

Learn your history please. there were no ‘so-called Protestants’ during the Crusades. All Christians were essentially under Rome or under the Byzantium Orthodox Bishops.
