I gave her a brief history of the evolution of the tartan and its relation to clans. She didn't care, but she no longer had ammo for her argument.

I didn't change her opinions, and didn't think I would. However, the other people in her group did have their opinions changed, and challenged her kilt-bias the rest of the night.

Attack the basis of the opinion - not the opinion itself.
Very good advice
