I think the whole issue boils down to respect. And not just respect for your tartan, but respect for the views of other kilt wearers... I personally enjoy having a connection to a tartan that I buy... but I don't HAVE to have it, it's just an added bonus. I do however try to at least know some history behind a tartan I might wish to purchase... But the big thing is... I don't really care what any other kilt wearer wants to do. If you want to only wear the tartan(s) associated with your clan, fine by me. If you want to wear every tartan ever conceived because you think they're all beautiful and you have not one bit of knowledge about Celtic history other than a few stats about Boston's basketball team and what you could glean from Braveheart, good on ya. If you want to wear whichever tartans look good on you and you respectfully learn a little bit about each one, I applaud you. All I ask for in return is the same. Why in the world should we tear each other down about who is allowed and not allowed to wear a tartan, when we're all promoting Scottish pride and kilt wearing?
