Watched Sami Blood last night (via a US public library Hoopla app).
Fascinating.
Don't have the Swedish title of it but maybe @Caesar has seen it and could comment on
the extreme prejudice against the Sami in Scandinavia, Russian.
I haven't watched the movie, and see the Swedish title is "Sameblod".
I don't know what the movie is about, but based on the little you wrote about the movie, I nearly already can understand some of the action.
Yes, sorry to say, the Sami were prejudiced in the early 1900's. Almost in the same way immigrants were treated in other countries at that time. They were ostracized and subject to racism. They were not accepted in the same way as the ordinary population, and had to colonize and many had to continually move around. The history of the Sami is poor, from a view of equality.
Around 1960s they were officially integrated into society. As you know, things aren't as good in reality as on paper. But things started changing around that period of time.
Without knowing for sure (I do not know anyone who is Sami, and I am not from that area), I believe the Samis now is fully integrated and are living normal lives.
Something else is incomprehensible to me, since we live in a modern age of equality. People are people, regardless of background.
