Transcript for 'Fat Girl Scene' From 'Louie' Strikes a Chord
We have the hottest story on "The heat index" this morning. The reaction to "Louie" blowing up. The harsh words resonating with plus-sized women everywhere. Abbie Boudreau has the story. Can I just say it? I'm fat. Reporter: It's the seven-seven so-called fat girl rant that some women are calling brilliant and brutally honest. You know what the meanest thing is you can say to a fat girl? You're not fat. Reporter: Actress Sara baker, who appeared in "The campaign," and TV shows like "Modern family" may be best known for her appearance on Louis c.k.'s FX series, "Louie." It really sucks. Reporter: Did you think this scene would strike a chord with so many people? It struck a chord with me when I read it. Reporter: Do you relate to what she had to say? I do relate to what she had to say a lot. I think there is this standard for women that's just so different than the standard for men. Reporter: Baker's character, Vanessa, asks louie out. When he says no, she thinks it's because of her weight. I'm making you represent all of the guys. Why do you hate us so much? Reporter: The lengthy speech about being overweight while trying to date now making headlines. I'm saying, have you ever dated a fat girl? Girlfriends, of course, talk about those things all the time. To talk to a guy about it is a different thing. And it can feel good to be like, this shouldn't be like this. And it sucks. Reporter: Fans showing their love on Twitter. Thanking baker for opening up the conversation. It was so pure and so honest. And again, something we haven't heard a lot of people talk about. Reporter: Baker, who does not usually select roles based on her body type, says this time, it was a good choice. This is done in an artful, beautiful way, I'm really happy I took the part. Reporter: For "Good morning America," Abbie Boudreau, ABC news, Los Angeles. And joining us now is body image expert and author of "Good girls don't get fat," robin Silverman. We enjoy having you here. Thank you. What is the key thing that's striking such a deep chord? When we see so much fantasy and fabrication of the truth and photoshop, a little healthy dose of honesty goes a very long way. We have a character who is saying to everybody, be honest with yourself, be honest with me. And realize by saying, you're not fat, you are not seeing me for who I am. And you're actually grouping me in and stereotyping me like everyone else. Tricky piece of writing for Louis C.K. What can men learn from this? I think men can learn that they need to break away from that term fat as meaning all of these negative terms. They need to hang up their hangups and be with the person they really care about. And finally, that this is not a women's problem. Stereotyping and discriminating against women, it's not a women's problem. It's everyone's problem. And don't be part of it. Both of us, men and women, can be part of the solution. Absolutely. Terrific to be having this conversation. Body image, and self-esteem, so important to get out there. If there's one final thought to our viewers, what would it be? When I'm speaking to my audiences, they tell me they don't see themselves in the media. They want to see themselves. When you see yourself, everybody feels Normal and accepted. Great -- A lot of sense. It does. Robyn, thanks. Thank you.
