Justine is interested in the bottom line of her business - Mumsnet. The more people she gets on here arguing the better. Good on her the Telegraph is good PR.
BUT, we all can see what is going on here, its as plain as the nose on your face.
Harry - Intensely jealous of his sibling, probably with mental health problems, naive as to how his "revelations" will play out, needing money, lack of insight into how much "life costs" when he is out of the Royal bubble, egged on by his new friends who are probably just counting the pennies and laughing at his gullibility. He has been astonishingly indiscreet, and breathtakingly idiotic in what he has disclosed. He's made himself sound like a prize numpty and staggeringly entitled. Utterly lacking self awareness.
Meghan - Red flags galore here, has fallen out with ALL her very large family, none of whom attended her wedding. Regular reports of her "being difficult" imply that she probably IS difficult. You don't get through as many staff as she has done without there being some problem, Sophie, Catherine, Anne, etc etc don't have the same. "Is it because I is black", well no, not really. There is very little that Meghan has seen that hasn't already been dished out to "waity Katy" and she definitely isn't black.
Mumsnetters are probably not far wrong to see an agenda with her - squeeze Harry dry, then divorce him. Frankly even if she did marry him for love, after the book I'm thinking it will all be over. He unfortunately has made them both look like idiots.
