Almost all of them are middle class. Many of them are educated and somewhat socially awkward. A lot of them are either nerdy, or have nerdy pasts, and can be annoying. But unfortunately, all of them — including the animated ones — are Caucasian. Worse still, only three of the females listed below are characters on shows currently on air.Not to mention that a lot of the characters are portrayed in problematic ways, like being depicted as man-hating or as comic foils to more important chauvanist male characters.
But the list is still fun to read. It warmed my heart to see Roseanne and Elyce Keaton from Family Ties on the list. And the best part about the post is the comments thread, which is bursting with more suggestions for feminist characters. If you take away the (somewhat rigid) requirement that they actually talk about feminism or identify as feminist, television somehow becomes a lot more promising. Also, see Aviva's additions to the list at Fourth Wave. She comes up with five more TV feminists, three of which who are women of color.
UPDATE: Melissa Silverstein at Women & Hollywood has more.
