A friend sent me this interesting link on Wiki that lists pretty much every ethnic slur there is in the English language, most of which I've never heard before. Why, they even list Bluenosers and Newfies! Some strange reading... something to offend everyone. I can only hope it goes a little way in desensitizing us to what are simply words.
So does this mean we have to consult the list before we say anything? Ben and Jerry's recently had to issue an apology and changed the name of their new flavor, Black & Tan Ice Cream!
