"It's a kilt, I don't play the bagpipes, I don't wear anything under it, Because it's comfortable, who cares if I'm scottish and I really don't want to hear about your family history"
I'm sorry, but I find this one just a tad on the rude side. If you're going to wear a garment that has a long-standing association with Scotland, you should be a good "ambassador" whilst wearing it and show respect. If you want respect, you have to give it.
