KHole really isn't an intellectual.
She fools some people into thinking she is as she is articulate and very assertive aggressive
However she can only see issues through the lens of black and white - Fat = Bad, Slim = Good, Perez = Bad, Alexander = Good, etc, etc.
And she is so belligerent in her delivery that people end up feeling railroaded by her. I think they give up trying to get her to understand there is another way to see something, or that different people have different experiences... and so it seems like KHole almost always wins every debate...
But this isn't due to superior intellect or cleverness. It is just down to sheer bloody mindedness and deliberate ignorance of any ambivalences or ambiguities.
I think KHole is well educated and she's not stupid per se.. but she's definitely not someone to admire for their intellectual rigour or curiosity about the world and how it works.
