It should be noted that profanity is a relative cultural concept. That is, what one culture considers to be profane may not be offensive in another. For example, various hand gestures that are perfectly acceptable in the USA would be highly offensive in the Middle East. Similarly, the word "bloody" in the UK carries a harsher connotation than in American English. Thus we should not be quick to dismiss quotes because they do not match what our culture considers to be profanity, especially in Western culture that allows horrific words, violence, and sexuality to be displayed routinely on public television. With this in mind, I offer some quotes by Martin Luther:
"Did I not tell you earlier that a Jew is such a noble, precious jewel that God and all the angels dance when he farts?" (On the Jews and Their Lies)
"He who hears this name [God] from a Jew must inform the authorities, or else throw pig poop at him when he sees him and chase him away." (On the Jews and Their Lies)
Of course "fart" was highly offensive at the time and "pig poop" (older translations say "sow dung") can be translated more harshly - I don't think I need to spell it out ;)
