I am reminded of a (quite real) committee meeting at Penn State about posting an agricultural image database to the web. At the end of the meeting we were absolutely forbidden from posting any pictures of slaughtering cows, because this could offend people of the Hindu religion. At no time was anybody of said religion consulted and several of the professors involved objected that without these pictures entire parts of their courses would be invalid.

If you go through life worrying that everything you do or say might offend somebody, you're going to do nothing but hide in your room eating, drinking, and breathing nothing. Of course doing this will cause you to die, and that might offend whomever discovers the body. :)
