Boys and men need to feel they can offer something positive as male people
Learning to drive a vacuum cleaner would be something positive they can offer as male people. But that's "women's work".
One of the reasons why I didn't learn to cook until I was in my late twenties is internalised misogyny: cooking is "women's work" and I don't do "women's work" because I'm "not like the other girls", in fact I'm not really a woman but a man trapped in a woman's body (see also: gender dysphoria).
If "that's women's work" deters a woman from learning tasks that an ex-bf (who is a fabulous cook) rightly dubbed "not women's work, survival work", then it's going to deter men from learning it too.
They like the idea of survival skills, of engaging with the wild, camping, making fires, stalking, acts of physical strength ( lifting, pulling, hauling, building).
So do girls! A huge driver of my internalised misogyny is how everything targeted at girls is pretty, pink, and pathetic. All the cool stuff is labelled as being for boys.
