The sad fact is whether any allegations are true or not they will stick. People always think "no smoke without fire", and when you read Skanky's post would you as a parent in that school allow your kids to socialise in B&J home? Would you allow your kids to attend parties, sleepovers or whatever in that house, would you always carry doubt that maybe this one time Skanky was telling the truth? You wouldn't risk it, the flip side of that is would you want B&J in your home, playing with your kids knowing the kind of accusations the mother makes all over social media, no you wouldn't, any sensible person would protect their family from even the possibility of false accusations. In her eagerness to take down KH she is isolating her kids from any little bit of normality, any friends, any extended community support and interaction.
As for Michelle, she is in a no-win position. If she posts about the kids it's all "how dare she, she is provoking" if she doesn't it's "She doesn't treat B&J as part of the family" MP entire role in this is to be in the wrong, always in the wrong, as KP is forever the victim. MP is not provoking anyone, it is up to KP to handle her own emotions and get a bleeping grip on her life, provide her kids with a safe, stable home without a never ending array of new dad's, get help for her addictions and her obvious personality disorder, but no it is easier to ring up The Sun to do a pap walk by some wheelie bins and pretend to be a "star". Doing what is right for your kids is too much like hard work for her.
