I agree with Joan, but this whole episode just proves out a well-known manosphere truism: that only a woman can publicly impart the (red-pill) truth about women---or any individual woman---without the customary opprobrium.
The fact that Lena Dunham is fat and unattractive is so gobsmackingly obvious it look an entire national media apparatus to get people to pay lip service to her "beauty". But her debacle on SNL may have been a turning point---people are smelling her blood in the water and there is now less cost to broadcasting the truth. The Empress never had any clothes, but it looks like it's becoming safer to actually acknowledging this.
It would be one thing if Lena Dunham had tried to make a career solely on her acting or writing chops. But that's not what she did---she tried to tried to seize the beauty mantle, too. That was always going to fail, on a long enough timeline, because boners don't lie and because genuinely beautiful women have too much to lose by her trying to move in on their turf.
She probably still has a place in the business. I've never seen "Girls" but apparently no one portrays the vapid soullessness and sheer selfishness of the modern American women like she does. There's a market for that. But it's going to get harder to insist on this "beauty" schtick---the jig is probably up on that.
