Why is camgirl a viable career? Why are there so many camgirls? Why are there so few camgirls? Why are there almost no camboys, and those that do exist are mostly patronised by gay men? What are the demographics of camgirls and their customers, and why? And so on.
No but seriously you already know the real answer, most of your readers should too, you just know it isn’t produced by straight Feminist theory. You have to mix in a little heterodoxy and some blasphemy to get there. Stir, pour over ice, drink, and then get banned from the gender discourse for thinking the unthinkable.
Joining the Transhumanists afterwards in a plot to finally escape gender by increasing the morphological freedom of humanity is strictly optional.
You’re right though. A grand gender theory does need to explain camgirls.
