Liz Jones is terribly self-absorbed and unlikeable, but it also seems obvious (to me at any rate) that she has some kind of mental disorder, so I do feel sorry for her, and don't think she deserves to have that kind of abuse hurled at her.
Have never been a fan of India Knight. I used to read her Observer column, and then her Sunday Times column, until I'd had enough. I was quite shocked on a couple of occasions to read articles where she'd said it was OK to smoke and drink in pregnancy - after all, our mothers did, and it didn't do their children any harm (an assertion quickly disproved if you google stats on the decline in neonatal mortality). She once said that if you smoked, it supposedly made your babies smaller, but she'd smoked and both her babies (this was before the third) had been over 8lb, so it was just as well she had smoked, otherwise they'd have been enormous. She also said that she didn't breastfeed as it made her feel like an animal.
This wouldn't have been quite so bad if she hadn't written a number of other columns attacking mothers who give their children junk food, because they were irresponsible.
I feel quite strongly that newspapers should refuse to publish articles stating things like "it's fine to smoke during pregnancy", which is so clearly untrue - as CP Scott famously said, comment is free, but facts are sacred.
