The problem I see is that far too many parents go down the "boys will be boys" route
This, in essence. I overheard exactly that line being used at a kids' party last weekend, where a slightly older boy was going round repeatedly smacking 6-year-old girls' bottoms. When one girl came to complain about this to her Dad, saying that her bottom was a private area, she was given short shrift with this response and the boy continued unimpeded, while being smiled at benignly by his own parents.
Social conditioning around this kind of 'trivial' incident is exactly where all the Gregg Wallace-style entitlement in later life stems from imo. I also see it regularly in schools I've taught in and still visit, where boys take up all the space in the playground and girls are confined to the edges - again, 'boys will be boys' was spouted in these contexts. In the class I volunteer in weekly, around 3/4 of the teacher's time and mental bandwidth is taken up dealing with a group of 6 or 7 boisterous, poorly behaved boys, while all of the girls and the less typically 'Alpha' boys sit quietly waiting to carry on.
What with this, porn and incel culture and the way the louder, more 'macho' boys are allowed to dominate in my DD's own class, I now strongly favour a girls-only environment for DD's secondary education.
I think boys are fab (DD's current 'bestie' is a lovely, kind, clever boy) and in many ways I feel sorry for what our society in its current incarnation is doing to boys and men as a group, particularly white working class boys, who I think are sorely misunderstood and underrepresented. I hate the dull, static primary curriculum, which I can see doesn't suit the livelier boys at all, and I wish more schools would have the courage to abandon the endless PowerPoints and teach more content through exploration, outdoor learning etc (I actually think this would benefit everyone, not just boys). And I can see very clearly that our utterly broken SEND system is impacting most severely on boys. But pragmatically, there is so much toxic masculinity around at the moment, and so many badly messed up boys and men, that I want my daughter to be given the chance to develop a strong identity as a woman before being exposed to the 'real world'.
