or..the OP is saying her DS in the name of feminism should undermine the allocation of work by the girls, and say 'i'm better at this subject than you, let me do the work and we'll all get better grades'. Or 'here, let me do it, love you dont know what you are doing'...
or..
her DS is standing back and letting the girls fix the car even though he knows how to do it, so they can learn themselves..
or..
he is sitting back and watching the girls fail because he is lazy and condescending..
or..
the girls know that OPs DS will score all the goals if they pass him the ball, and the team will win because hes a great goal scorer but they dont want him to get the glory so they dont pass to him. wjen the team loses, they blame him for 'thinking he's so brilliant but he's not'.. but the team have lost. OPs mum says 'takle the girls and take the ball off them and score. OPs son does this and the team wins. The girls hate him more. the manager berates DS because 'he doesn't understand teamwork' DS says 'i fid what had to be dobe to get the best result for the team' DS is dropped and the tean feels better..but loses every game.
or..
DS is the expert in the team. the projevt is run by non-experts. he can expose them as non experts by giving the right answers, or doing the work himself, or make them feel better about themselves by pretending their wrong answers are right, or let them do the work and advise and guide.. but obv without being in the mansplaining, dominant, or 'MAN = RIgHT' position even though in this case man and expert are in the same body.
The question is, should he supress being 'right' in order to offset historic dominance by men two generations before him, or be treated as a genderless actor with skills in the present, and which is more feminist...
but also choose which perspective is more useful..the wholistic team perspevtive, the boy is to blame perspective, tge girl is to blame perspective, the individual that we have access to is to blame, or the group v individual perspective..
