You have to remember that Linda was part of this brave new world. Upon visiting the savage reservation with the now director, she was stranded there after having suffered an accident. Because she was part of the new world, Linda was programmed to think that everyone belonged to everybody else. However, her promiscuous ways are rejected, to say the least, on the reservation. Linda has had sexual relations with the women's husbands (or she has tried) and therefore her unorthodox ways are seen as abhorrent in this new lifestyle.
