Louie C.K. has a scene in his sitcom where Vanessa, a woman who wants to date him, calls Louie on the carpet for his fat-laden refusal. The Jezebel article gets it right:
While it might read like another “sad fat woman puts on a happy face to hide the pain” trope, Vanessa — in her delivery — is completely lacking in self pity. She doesn’t hate being the fat girl, but she hates what it means to other people and she hates that society has dubbed her as not being good enough to even be the girlfriend of a schlubby divorced dad in his forties.
The issue is our culture that demeans fat people; the issue is not people who are fat. To read the script and view the scene, see Jezebel.
