I agree with some of what she says, but some of her examples also sound like oversensitivity. The elevator example – the idea that her fancy clothes should label her as an associate and that the poor girl who didn't notice them is somehow a racist – irks me the most.
I really lost her when she mentioned that she was surrounded by Rob Ford supporters. I'm white as they come but cannot imagine blending in with that crowd! 
I'm sure she has many valid points – clearly hiring practices were flawed and I'm sure that there are a good number of blatant racists on Bay St. However, I think that too much of a concentration on the subtle or accidental (or possibly imagined) "racism" that she mentions in many examples is a distraction from some of the more serious issues that she brings up.
