Royal BC Museum is in Victoria, not Vancouver. There is a world of difference between the two.
There is a museum in Vancouver, across the street from the University of British Columbia campus, which has a lot of interesting "First Nations" artifacts including totem poles. I don't recall the name of that museum offhand. I have been there and was wondering how anyone could find any of it offensive. But to the Perpetually Indignant (P. J. O'Rourke's phrase), there is always something to be up in arms about.
