I'm a far outside observer. IMO Aimee has had what could be described at the bare minimum as a less than ideal childhood. The behaviour the father exhibited (trying to tread carefully here) is not something that is a random occurrence. That level of abuse takes time to reach, there will be many instances to slowly build up to that.
Frankly, the mother has had some questionable behaviour. Which may explain the involvement of social services. Some of what I've read on the internet is really concerning, if true, there appears to be shades of MBP.
Imagine the nightmare childhood of for want of better phrase is MBP meets paedophile (eggshells but what other name is there for someone charged and convicted of CSA).
As much as Aimee's behaviour is frustrating. I can't help but feel sympathy for what I suspect is a very damaged child deep down. Do not mistake this as defence or justification of her behaviour. We know that many children subjected to abuse fight to move on from it and have fulfilling lives, some go on to try and prevent what happened to them from happening to any other child.
But the hard question, is how do we prevent the child so well groomed, from continuing the cycle? How?
Still all the above said. Why with such easy access to the internet, a google would reveal so much, was Aimee selected as what it essentially a spokesperson for Autism? Surely they could have found a Trans Autistic (Autistic Trans? so hard to guess what phrases are offensive or not) person without such a controversial background.
