I saw this on the sci.lang.japan newsgroup and thought it was pretty cool.  Mr. Brett Robson used it for his signature

People are all exactly alike. There's no such thing as a race and barely such a thing as an ethnic group. If we were dogs we'd be the same breed. George Bush and an Australian aborigine have fewer differences than lhasa apso and toy fox terrier. A Japanese raised in Riyadh would be an Arab. A Zulu raised in New Rochelle would be an orthodontist. I wish I could say I found this out by spending artic nights on ice floes with Intuit elders and by sitting with tribal medicine men over fires made of human bones in Madagascar. But, actually, I found it out by sleeping around. People are the same, though their circumstances differ terribly. Trouble doesn't come from Slopes, Kikes, Niggers, Spics or White Capitalist Pigs; it comes from the heart.
