A couple months ago, I got an email from a friend of mine that is involved in "AIDS journalism" and associates with a lot of PC people, a long speech, asking that we sign an online petition against this law coming to Parliament in Uganda.
So I hit Reply To All (it was about 30 people in the address list) and said "Do they have a law against sex with animals?" (Thinking of the goat fooking that seems to be so common in Africa.)
I got two or three undeliverable messages (one from someone in the UN) and the next day I got an email from a pastor or minister in Uganda, addressed to me and to the guy who'd sent the mail, saying "Please take me off your address list."
