Ms. Doyle, I read your piece and I have to say that it does have some very valid points; however, I can't escape the feeling that you're concentrating on the trees and failing to see the forest.
Part of what I love so much about Tina Fey is that she mines comedy from the distance between how WE see ourselves and how other people see us. And if, like the saying goes, comedy is just inverted tragedy, then you can't truly have moments which really connect with the viewer without that sour-sweet element of tragedy.
So let's look around at the OTHER things that help illustrate the difference between how we see ourselves and how the rest of the world sees us, perhaps? Your personal life vs. work life is one of those dichotomies. As is your romantic life vs. how you think your romantic life SHOULD be.
If your definition of a feminist is (for example) someone who is always demonstrating good role model behavior for girls, then any "feminist" character you create will generally tend to hew to that model.
Realistically, feminism isn't a monolithic and singular idea any more than nationalism, or any other such large concepts. It comes down to individuals working out for themselves what it means to be a feminist. And as a person who understands that that kind of reaching will also include stumbles, falls and setbacks, I'd hope that we can stop and be able to laugh at ourselves as people first. Tina Fey models this in a beautiful and funny way, consistently.
