^^I agree with this.
I've been thinking a lot about coercive control recently and how it can look, primarily because of the situation with Neil Gaiman and his revolting behaviour.
I agree with PP that even the most intelligent women can end up getting sucked in, unable to stand up for themselves against the most depraved behaviour. And it can look a lot like consent at first glance, so it's confusing to view from the outside and easy to misunderstand. But it's not true consent, freely given. The coercion is key.
The only thing I'd say with Bianca is that I think this is her kink too. I'm not convinced it's coercion. I've seen her when she's been out with her mum and sister wearing extremely revealing clothing that doesn't look comfortable in the slightest. I've also seen her wearing just regular skimpy/tight clothing when with them too so she would seem to have the choice? Also, pre-Kanye she had a history of wearing revealing/tight clothing although admittedly not to this extent. I think the whole facial expression is part of the performance.
I'm not convinced this is completely all on Kanye, much as I'm reluctant to cut him any slack. I think it's a combined kink that she enjoys too. Ultimately we can't be sure but I think the balance of evidence suggests that's the case.
Pair of fucking idiots. Shows that money can't buy class.
