>>>Obviously there are significant racial tensions between gypies and ruthenians.
I wouldn't say that's the case at all.
My family comes from about 10 miles from Mikova (the Warhola family's village that's the setting for most of Absolut Warhola), about 15-20 miles from Medzilaborce (where the Warhol Museum in the movie is located). My impression, having visited the area 5 times since 1996, is that the Roma and the Rusyns live mostly separate lives of peaceful coexistence. There is no particular "tension" among them except that in *some* villages the Roma are marginalized and live on the outskirts of the village (in some cases in squalor). In other places, they speak Rusyn (rather than Slovak), they are members of the local Greek Catholic or Orthodox parishes, they participate in local commerce (buying and selling), and there is even intermarriage with the villagers (unusual but it happens).
It's in the large towns (like Medzilaborce) and the cities (like Presov and Kosice) where they are more like "untouchables". My Rusyn and Slovak friends from the cities all report admit pretty much a similar outlook: they have no Roma friends and while they don't seem to harbor resentment or hostility towards the average Roma people, they do have some prejudice and suspicion against them.
The scene from the movie, with the Roma complaining about the museum supposedly barring them from entry, is not due to ethnic tension per se (the particular Slav ethnicity of the museum staff is irrelevant); rather, it is more similar to a "back of the bus" and "whites only" attitude that the Roma, unfortunately, seem to have earned.
