I'd never heard of this person, but they are obviously very into feminine stereotypes.
Not sure to what extent this is accurate:
Yes, granted, Nikkie does all the glam makeup and hair stuff and Instagram looks.
But: she's also a beauty icon despite really falling short of what is considered "conventionally attractive" for women: way too tall, far too big, round faced and blotchy skinned.
What I really, really like about Nikkie - despite her personal style being way too over the top for my own sense aestethics - is how upfront she has always been about what she looks like without all the gunk. Her Power of Makeup videos, in particular, expose the lies behind conventional beauty pretty spectacularly.
I've never felt that Nikkie thought "womanhood" depended on looking like an Instagram model, and have always seen her as someone who was radically blunt about what real women look like in everyday and just how far removed from reality that high glam look was - however much she might personally enjoy and financially benefit from managing to project it.
I actually really like Nikkie for this, despite lacking both the talent and the desire to achieve her looks.
Also, all trans politics aside: blackmailing people about personal matters is the hallmark of an irredemable arsehole.
