I don't get it, either.
You know, I do hear what saudade explained (I myself think it'd be better if the girls were used equally), but I think that the hatred has reached a ridiculous level.
This forum has come to a point where Candice isn't granted anything and no matter what she does, people claim she wouldn't deserve it. She doesn't deserve to be an angel, she doesn't deserve to be on Forbes list, she doesn't even deserve her salary and so on. And of course this must be repeated again and again and again... People never grow tired of pointing out how she arches her back and how silly she looks in the videos.
Seriously, it's not her fault that VS overuses her that much. VS might act as if she's the second coming, but the people here act as if she became death, destroyer of worlds...
