*Are you kidding me? Primary schools are the most namby pampby, kind hands, that's not ok, no bulldog at break times, gymnastics and dance for PE environment on earth. Totally unrewarding for most young boys in my opinion.
Maybe if you are seeing those things, they are a reaction to normal boyness being supressed like it*
I partly agree with this. I would say that the primary school environment is now way too static and screen-based (it's death by PowerPoint in many lessons I see) and is squashing the natural urge of all children - not just boys - to move around and explore. This needs to change IMO - more things like Forest School and outdoor learning would be great for everyone, and reflects the kind of experiences I had as a kid.
Conversely, boys, in my experience, are still allowed to take up more space in playground than girls at break times, and are often pandered to in things like class reading choices - so much hand-wringing about how we can only choose books with a male protagonist, or with football/war themes because the boys will disengage from anything else. The girls are expected to suck this up.
And what is 'normal boyness'? As I can't see any way in which using 'kind hands' (which generally just means not manhandling, grabbing or assaulting your peers) or being told certain behaviours aren't OK would contravene 'boyhood'.
My DD's school has one PE lesson each week based around ball skills/team games and one based around dance, gym and movement - a fair balance I think.
