It's interesting to think what might have happened if every girl who wanted to take that shop class just found another school that allowed for it instead of putting up a fight. I'd like to think that all schools would eventually abandon the arbitrary restrictions left over from outdated gender roles, but it's not impossible that without repeated pressure from a growing number of frustrated parents/children they'd continue to keep that shop class male-only hurting those girls who weren't able to switch schools

I get that it's hard to ask people to think of the wider implications when they've got their own life to consider though.
