First, I am impressed bob didn't get into a whole "thing" about killing off Maude Flanders to add more character depth to Ned and their boys. Second, Bob left out the parts of Maude's personality that, compared to Marge, made her MORE progressive and accepting of others' differences. She wouldn't have lead the protest of Michaellangelo's David if Marge didn't get the protest-train rolling on Itchy & Scratchy, and now protesting things she doesn't understand is the closest thing Marge has to a steady job. Sure Maude helped lead the charge on the burlesque house, but she was swayed by the song-and-dance number like everyone else in the mob, but Marge wasn't (Rev. Lovejoy: "Thanks a lot, Marge, that was our only burlesque house!"). Also, as one of the "Investorettes", teaming up with other women to make oodles of money sounds rather feminist* to me, and they all voted to kick Marge out for being her usual wet-blanket self.
Wow, I am NOT making Marge sound like a positive role-model.
*Speaking as a white heterosexual human male, I have only the most basic understanding of feminism, that it's about women's freedom of choice in their lives and equality with men under the law.
