If you want to be angry, sure, and I think parents should largely be able to choose though that's difficult with the turnover we're seeing in many caring professions.
I'm not sure it's pointed at the right place when the issue is that this nursery entirely failed basic safeguardings, and these failures seem to keep happening due to funding leading to lack of staff. No 17 year old should be 1:1 the way this boy was.
It angers me when women jump to the defence of men and throw women under the bus and say they do it too... when there is a massive difference and actually, women don't do it the way men do.
I don't view it as throwing women under the bus, but the importance that safeguarding not rely on the concept that certain people are safer due to their demographic.
Plenty of us remember when people would call clergy, medical professionals, and similar safe not only because of how hard they worked to get into their positions and so on, but because if we look solely at the stats, perpetrators convicted are overwhelmingly men of lower socio-economic status. That mindset failed many.
Yes, males are far, far more likely to do these crimes, but our safeguarding needs to not rely on females being safe. Calling girls and women safe has also repeatedly failed.
I'm one of them. It's why I always recommend to my kids to take someone with them to medical appointments, never to rely on another medical professional to be the chaperone/support (I was abused with two chaperones in the room - they helped hold me down, everyone involved was female, they laughed about how they were teaching pregnant teenage me a lesson while I was sexually assaulted and left heavily bleeding). The safeguarding there failed because they were allowed to close and lock the door of the room I was in and attached to an IV. In nursery situations, as many have said, I don't think any nursery worker should be 1:1 with children in the way this boy was and safeguarding needs to go far beyond just not having boys and men. If parents want to pick a female childminder or other carer, sure, but we can't rely just on carers being female and really, I don't think nurseries can or should rely on that either.
