an Upper East Side socialite who has been fawmed over in NY media circles since she was a child and has admitted to some odd sexual experiences involving her younger sister

Are you talking about a fictional character or an actual person here? The former wouldn't be great (especially since as I understand it Girls is supposed to have a very realistic tone), but at least it wouldn't be the latter.
I'm talking about Dunham herself. Girls actually DOES have a fairly realistic tone in how it portrays some issues common to young women (at least in my interpretation. It's remarkably blunt and clear-eyes about things like sex, dating, relationship issues, body positivity, etc) but I've always chafed at its celebration as "THE show about Millennials!!" When it really just tracks four privileged New York girls and their experiences. Not that it's a terrible show, it's just it's not a quintessential story of young people like its promoters want you to think it is.
As for Dunham... While I lean towards "some" of her views politically, I chafe at the way she's rocketed to the top of the industry thanks to assists from heavy hitters like Judd Apatow, especially after I read up on her charmed upbringing amongst some of Manhattan's heaviest social hitters and how the New Yorker used to do reports on her extravagant birthday parties. As a child.
