This point of view annoys me to no end as a Canadian who has walked the Camino; or parts thereof, on five occasions, wearing a kilt. I even had a women advise me that I had better move along before her husband arrived as they had "heard" of me and as I had no right to the kilt, he was threatening to "rip it off me".
I spoke to both of them and advised that I had traced my family, from parents, back to 16th century Scotland. My question as to what was the statute of limitations on being proud of ones heritage, seemed to stump them.
As a country of immigrants, we see a variety of "national dress" at various festivals throughout the year. Yes my country's original inhabitants have traditional dress. However, their pre-colonial attire would make for an uncomfortable walk I suspect.
