It is simplistic in my view that something as complicated as toxic masculinity can be addressed by having a teacher that shaves and talks about football
No-one is saying that!
There aren’t many male role models in wider society and, most importantly, those that are relatable/accessible to children. Politicians, actors, musicians, sports people are not role models. GP, pharmacists etc are not role models - a child (if lucky) may rarely see theirs. Someone in the army is not a role model and National Service is not a way to bring up young men.
Scout leader perhaps and this brings me back to my point about the loss of youth clubs. Unfortunately, I don’t think many teenage boys would join the scouts.
Boys/children just need decent men who are a regular part/constant in their lives modelling how to be decent men. Ones who work with their colleagues, male and female, with mutual respect, can engage children, turn up to work on time, don’t swear, show consideration, humour, interest, engagement. All the qualities a good teacher should have.
They don’t need special training, just be a decent man - many children lack this in their lives.
