The scribe penned a reply to a comment posted by a reader of TV writer Ken Levine's blog. The reader, who called herself Tarazza, criticised the box office hit for "the lack of a decent portrayal of women".
"I get it. It's not hard to understand how bright women could be appalled by what they saw in the movie," Sorkin wrote. "But you have to understand that that was the very specific world I was writing about."
The Emmy winner explained that his movie focused on the early days of Facebook, where the company was almost wholly male-dominated.
"I was writing about a very angry and deeply misogynistic group of people. These aren't the cuddly nerds we made movies about in the '80s.
"They're very angry that the cheerleader still wants to go out with the quarterback instead of the men (boys) who are running the universe right now."
According to ABC News, a rep for Sorkin confirmed that he had indeed written the response.
