Everyone and their brother with an ax to grind against Catholicism repeats urban legends about the Crusades.

n.b. You will note that comment moderation is back on. The Tenth Crusade is being pursued by individual who believes there is an implicit blogging commenters freedom granted by the United States Constitution. I am apparently transgressing this constitutional freedom when I delete posts opining that Catholics are butchers and mass murderers who do not give to or serve the poor. He has threatened to call the blogging police. I am barricaded in my home. Send Ramen noodles.
