As others have said, the point is less whether or not Aaron Sorkin is misogynistic, but whether the show is. I have little interest in exploring Sorkin's psyche. That's a dangerous path to take. I wouldn't even want to say that The Newsroom is consciously or purposefully misogynistic or sexist. But it is.
The show has waaaaay too much emphasis on "great men", and the crazy women that support, or thwart, them. That second episode utterly destroyed the Mackenzie character, having her debase herself to 'prove' that her asshole ex and boss is not in fact an asshole. Both of the main women on the show just happen to be extreme klutzes, emotionally unstable, and in constant need of men supervising or saving them. And of course this whole adventure is kicked off by a dumb "sorority girl" who is then brought back up in episode 2 for no other reason than cementing the impression that she was truly an awful member of society.
Based on the previews and the advanced reviews of the next two episodes, I don't think any of this is changing. The show undoubtedly has problems with women. I'll leave the judgments on Sorkin to those who know him.
