They hate her. Standard stuff really as she's fairly young, pretty, successful and strong willed. There's always sneering articles about her and unadulterated hatred in the comments section.
This, though, I feel is fucking low. Questioning women's parenting is something the Mail and Mailites do and I find it pretty damn reprehensible. It's obviously classic sexism and gender norms stuff but I think they know it's a very spiteful way to really "get at" a woman they don't like.
Holly Willoughby sparks a FURIOUS parenting debate as she is trolled by 'mummy-shamers' for night out at The Streets gig

As just mentioned in another thread. This isn't about her being "trolled" and the Mail simply reporting on it. This is about the Mail being really fucking nasty and using random Tweets to back up their own hit-piece.
Mailites don't like it. In nearly every other article about Holly they're very keen to question her parenting skills and how much time she does or doesn't spend with her kids. But, as with other topics, when they're told in black and white what to think/say they aren't so keen.
