Well, because I read a TON of interviews with the show’s creator and stars.

For instance, in this Vulture interview with B.D. Wong (apparently Vulture wasn’t hip to the capitalization issues):

"You very rarely see a transgender actor playing the part of a grocery-store clerk without having to say, “Oh, look at that trans person.” They aren’t ready for that yet. They don’t think the nation is ready for that yet. Sam said, “She is transgender, but her transness has nothing to do with anything.” Sam then told me the irony really is that Whiterose is in disguise when Whiterose is a man, and not when Whiterose is a woman. At the end of Wednesday night’s episode, when Whiterose meets with [Evil Corp CEO] Philip Price, Whiterose may or may not be suppressing all of the femaleness of her to have these conversations with Price. That is a very radical concept, which I don’t know if we have ever seen before. I made it clear to Sam that I am not comfortable with the idea of masquerading. He said, “If there is any masquerading at all, it is Whiterose masquerading as the businessman working with Philip Price, not the reverse.” That, to me, was interesting. I don’t yet know what he means by that, and I hope the show goes a bit further with it."

Who knows if whiterose is also closeted from Phillip Price, even if we are pretty sure that Price knows that Zhang is whiterose., why would whiterose have to be in disguise as a man at all? Why would he be closeted from Price (who knows the history of the DA) but not from China?

Not convinced yet? How about this Entertainment Weekly interview with Sam Esmail about one of my favorite scenes in the history of Mr. Robot:

"You’re right. There is a sadness, and I equate that with passion. She’s going through this inner struggle with her identity. She feels so much like one person, and she doesn’t feel like she can be that person. That’s part of her passion. She wishes she could. I think what she sees in Dom is that same notion. We haven’t gone down Dom’s path yet, but there is something about Dom that has that same sadness, the same hiding behind the mask. Is she the person she wants to be? Does she feel like she can be the person she identifies with? What I love about it is that Whiterose always goes to the background for people. She doesn’t talk to Santiago, who is the head figure. She goes to the person that she sees is a little more cunning, a little smarter and more on her game, but just doesn’t fit into her identity as well as she could. I think that’s the connection Whiterose feels with Dom."

Why in the world would whiterose feel like she couldn’t be whiterose unless she was closeted by her role as a Chinese defense official? Why in the world would she identify with Dom’s identity struggles if she weren’t closeted?

Minister Zhang is the outfit whiterose wears because she feels that she has to.

I am pretty sure that I have read a few other interviews that suggest this too, but I must not be on my research game tonight. I will add new ones in later once I locate them again.

Anyway, it is my prediction that the person represented by the password whiterose is a chaos agent using her authentic power as Zhang the Defense Minister of China to help her sub-national group known as the Dark Army.

Sometimes the interests of the Dark Army and the Chinese government align and sometimes they do not.

Sometimes the interest of the Dark Army and E-Corp align and sometimes they do not.

Sometimes the interests of the Dark Army and Elliot, Tyrell, and Angela align and sometimes they do not.

The only thing that I am 100% sure of is that the Dark Army is playing all of the principles off of each other in pursuit of their own self-interest.
