Here are some one liners...
The French Religious Wars. Remember the Alamo -- The Hugonauts take one in the neck, and they bring it right back to the French Catholics. A lot of people are going to remember this one... just like the Armenians remember genocide and Texans remember the Alamo.
The Witchcraft Act: You'll Swing but You Won't Burn -- The laws are changed to require actual proof of damages before a witch is hanged. I also talk about the Salem Witch Trials.
Book Burning and the Black Legend of Spain -- The Mayans have their books burned for backsliding into idolatry. I also talk about the Black Legend of Spain and how propaganda works.
