I have written previously about old odds and ends I've found in the cabin, and how surprisingly often they featured some over-the-top ethnic stereotyping. Here's one which is pretty specific: Mosquito repellent with a brand that plays on preconceived, though in this case mildly benevolent, notions about sami, previously known in english as lapps.
Like "lapp" the term "finn" is considered derogatory today, so this bottle seems very odd. A non-sami will find it more quaint than maddeningly offensive.
Calling a finnish person "finn" is another matter. It's fine.
It's a polar thing.
I have decided I'm going to call people what they want to be called. This becomes sort of silly sometimes, some in Alaska prefer to be called Eskimo but would be called Inuit in Canada, so what's a qallunaaq to think. But in general, it seems like the thing to do.
