I don't know how she would phrase it because I don't know her or her writings.
Btw, she definitely got plenty of those, since she's writing for the New Yorker. If it was really that deep, we could look into her articles and see exactly what she says about Black men, white men, and all these topics. That'd be a more serious effort than projecting coli fantasies on a 2014-tweet describing her past interracial relationships (and not even taking a dig at Black men).
But it's not that deep. What I'm saying is that she's clearly giving a simple description of reality. "Black men's hunger for ass" is a stereotype that exists, no? And even if it's the wording that's bothering you, Black men are animalized when it comes to the desires projected on them, especially the sexual ones, wouldn't you agree?
So again, the sentence is no ground for outrage unless you project every coli nightmare on the author. And like I said above, the only basis for this paranoia is an old harmless tweet.
