Three problems:
1. Lena Dunham is a sexist hateful, wahhabist ******** of sarkesian proportions...
...and also a general classist, racist Anglosphere c-word, who probably thinks you don't have indoor plumbing. Because Greece.
You know, white coastal American female and all that.
2. You may be aware of whatchamacallit... doctor games. You know, when small children pinch each others parts and stuff. So you may judge where the following files:
Well, Lena Dunham basically fingered her sister, bribed her sister into all sorts of behavior, was quite happy when her sister would snuggle up against her in bed and used the opportunity to masturbate whence she had fallen asleep.
This type of behavior started when Lena Dunham was 7 and Grace Dunham was 1.
It ended roundabout 9 years later.
We don't have to allege this. This is supposedly extensively described in Lena Dunham's memoir.
3. Speaking of which: In her memoir Ms. Dunham also alleged that a "campus Republican" named Barry with a beard raped her at Oberlin. But since we live in the age of big data you can't just throw stuff like that out there in a book that roughly every pathetic Clinton voter is going to buy.
The yellow press found a complete rando guy matching all the criteria in about 5 minutes. The ******** scum that dominates social media was very nice to him (no they were not).
Dunham's defense can be roughly paraphresed as: "1. It was a joke. 2. No i was really raped but we used a pseudonym, duh. 3. Everybody who is criticising me is a sexist Republican."
She (semi-)apologised to the actual rando Barry in a Buzzfeed article. Like two months later.
How "cis-fascist" of me not to like her.
