Boys on the Side
Well this film very obviously flirts with the ideas of interracial friendships and lesbian love by simply playing out the way it does. The very sincere acceptance of all three women of each other and the solid bond they share is obvious, even when some of them are fighting.
However, this is also why the movie skirts around these issues. They are never discussed openly or seriously. The only time a character is shocked at race or sexual orientation is when Robin's mother finds out who Jane is. But this exchange is meant to be humorous, and Robin's descriptions are vague at best. She is not focused on her mother when she tells her who Jane is and does not realize the apprehensions her mother has. So the casual acceptance of the relationships dooms them to be non-issues in the film.
