Her appearance and weight are irrelevant, and if she was a popular, loveable and famously nurturing person like say Claire Rayner, that same appearance would be seen as warm and embracing.
But, apart from that, I think the article makes some valid points. I remember well reading that thing about being unable to hug her mother on her deathbed and thought it was not only very sad, but really telling and hugely relevant to the kind of thing she puts in her books. And I think it's important if her methods, which I do regard as cruel, actually arise from her own psychological difficulties rather than from any scientific basis - I think people should know that.
