Now, I'm not saying my opinion is the only correct one -- far from it. But not everyone who wears a kilt has the "cause" of its adoption as another piece of clothing. For some of us, it is a symbolic garment.

I respect those who differ from me, and ask the same in return.
No sweat. To me, having Scottish ancestors, there is a bit of symbolism there, as well. I don't see that as a reason to keep me from wearing a kilt to the bar, the grocery store, or a Halloween party, though. To each their own.

So I wear my kilts daily, and I'm not interested in having it equated to a costume.
And you don't have to wear it as a costume. I don't see the point in getting torqued off at someone who is wearing a kilt for Halloween, though (assuming they aren't playing some awful parody of a Scotsman), anymore than I would get po'd at someone dressed up as a librarian.
