I must come from a different planet?
I really must come from a different planet or something, I honestly cannot see how anyone can take offense for someone else playing dressing up in a style that is over 500 years old. That would be close to 20 generations ago. If your taking offense over that, you need your head read!
What next, being offended at the Danes for dressing up as Vikings (Vikings raped and pillaged large parts of Western Europe for centuries! boo-hiss!), or being offended at the Italians when they dress up as roman legionaries (the romans conquered Europe killing thousands on the way! Evil bastards!)?
Utter tosh!
