They've been discussed on a few threads and I think they are yes. She has acknowledged some of them, she was angry and hit back harder and less sensibly than she might have. But, to be honest, who cares?
Very few people who do things the rest of us are too scared to do are thoroughly nice. They have to be more, erm, mercenary(?) than most in order to be as belligerent, as tenacious, as determined, creative and hard nosed as they are!
So I'll take a flawed Posie Parker, whose flaws consist of being less than nice occasionally, of being less than wholly PC, inclusive or restrained, not to mention patronising and smug (loved the look on her face when The Haddock tried and failed). I will thank her for being in the financial position she is in, so she can do what she does and for doing it for women like me, who may not yet have found the necessary back bone to join her publicly!
