It's a big part of it. Cynthia got as far as she did in politics by cultivating a public persona that could well be summed up in the phrase Black Bitch. Her abrasive in-your-face style, far more than her stand on issues, is what fired up her core-constituent voters. But for a white colleague to admit that he responded to her in exactly the way she wanted is very, very unacceptable to the PC crowd. I expect he'll end up having to apologize to her.
"I mean, she was such a bitch," he said.
I wish he would say what he really felt. LOL.
