I don't think gender makes a difference, I just think that much higher standards of behaviour are expected from girls.
Misogyny, innit?
I'd agree with that.
I sometimes wonder how much conflict girls experience comes down to an expectation that girls are nice, pretty, compliant, don't take up too much physical or emotional space, help out, don't make a fuss.
I also wonder how much the idea that boys are easier comes down to the number of parents who allow their boys to dominate spaces, excuse poor behaviour in boys because "boys will be boys", and don't get into conflict with their boys because they assume boys are wild, boisterous, unruly, and incapable of emotional skills.
90% of the threads on here about gender disappointment are people devastated that they're having a boy, and when you read what they're wanting from their imaginary baby girl it's a play thing, a doll, someone to be their best friend, an accessory that's theirs for life and won't go off getting another woman in their life etc. There's a lot of women who talk about not knowing what to do with "boy" interests, but they really want a daughter to do girly things with. The fantasy daughter is really there to play a bit part in their mother's life.
