How does Song's opinion of Madame Butterfly differ from Gallimard's?

Song sees the story as ridiculous. She believes it is an imperialist's fantasy to show the Asian submissive to the dominant white man. Gallimard sees it from a more romantic perspective; simply as a woman who loves a man unconditionally. Gallimard loves the idea of a woman who will devote herself to her man no matter how unworthy he is.
