It just so happens that my three favorite kilts (of the past few years, at least) are in tartans of my clan (Donnachaidh). However, if I were a member of a pipe band that utilized uniform tartan kilts, would I turn down the chance to play with such a band if I were to discover that they wore kilts in a tartan traditionally ssociated with a clan which was historically inimical towards my clan? Probably not. I don't live in Scotland, obviously, and my choice might be different if such an option were to arise in this latter situation. There are some tartans I doubt I would wear, but for the most part that's an expression of personal taste, relating to the color, the sett or just how I would look in such garb. Thanks to the powers that be for allowing human beings the luxury of personal taste. Even if it could possibly be argued that for some of us, most of our taste is in our mouths. . .
