Even if she's joking/writing for effect some of the time, now and then she'll say things which are just so despicable as to be unbelievable. Example - some years ago she wrote that she was quite relieved when her mother started showing signs of Altzheimers as it meant she didn't have to worry about her (mum) telling someone her (Jones') true age. Even as a joke - and I don't think she actually has a sense of humour - that's a horrible thing to say anywhere, much less in a national newspaper. And yes, she does seem to trylu hate anyone who has a nice family life, children and friends. In short, everything she doesn't.
Further, she persists in telling complete lies: she claims not to have had a holiday in 30 years, yet her books and articles going back to 1999 are full of her going off to Nepal, Italy, Tanzania and the like. Possibly her worst lie was when she claimed that in response to an article that was published on a Sunday, she got a sackload of mail the following day (this was the cheques, etc., from pensioners). There haven't been Sunday collections in the UK since October 2007.
Some folk here have said "well, she loves animals so she must be OK", but the evidence is that she likes animals for their unquestioning loyalty, but when it comes to making a hard decision to put them out of their misery - for example, a chicken that (allegedly) had cancer - she'd rather pay silly money for equally silly holistic remedies while the animal continues to suffer, for months if not years. That's not love, that's close to being selfish. She also seemed surprised when the locals weren't happy about her dog killing a sheep.
Finally, and worst of all, she's a piss-poor excuse for a journalist.
