Can't help wondering if people don't like her partly cos she is young, beautiful, smart, successful and sexually liberated
It really annoys me when this old cliche gets trotted out, because it is a crap argument.
In fact, Luisa used it herself in the Apprentice, saying people didn't like her because she was so beautiful. 
No, the reason people dislike Luisa is because she is a bully (see The Apprentice) and a shit-stirrer. She can also give it out but can't take it back.
What she looks like is irrelevant, it is her behaviour that people object to.
