Awesome details on religious satire in history. From the article:
"If you want to see truly shocking anti-religious cartoons, you have to go back to the sixteenth century. Near the end of Luther's life, his propaganda campaign against Rome grew increasingly vitriolic and his language grotesquely pungent. He took to calling his ecclesiastical enemies 'asses,' 'dogs,' 'pigs,' 'blockheads,' 'basilisks,' and 'pupils of Satan,' and the Pope himself 'Her Sodomitical Hellishness' and 'fart-ass' (no, it doesn't sound much more dignified in German—fartz-Esel). Eric Cartman would be in awe."
