It's diabolically brilliant in its simplicity.
And I'm not talking about the twitter drones who vomit up the talking points as easily as they say orange man bad. Those people are little more than bobble heads that manage speech somehow.
No, I'm talking about the thought leaders.
As long as the person is doing what they want and is given accolades and public opinion is in their favor, they can sing the 'woman's' favor and call people critical of them misogynist and buzzword, buzzword, buzzword.
The minute that 'woman' fucks up or steps outside the plantation, BAM! They're a man again, and it's all the fault of the patriarchy.
It's basically win-win. They can play the girl-power card when they're up and patriarchy poker when their down.
I don't think your theory is correct because if it was just the privileges of being a transsexual that keep them in line, the thought leaders could just use the same strategy with some other title of nobility with less turnover.
I think they push transsexual bullshit because it inherently makes people more loyal to them. It's not just a eunuch's inability to sire children removing a potential challenger for his loyalty, as it was in ancient China, but also the fact that a transsexual who loses faith in your ideology might not want to keep on living and so will die instead of turning against you.
It really is the ugliness of Marxism distilled down to the purest of spirits...
You're whatever you want to be so long as you fall in line, but the minute you step over that line, you're nothing.
