Boys and girls are not the same above the neck. Even when they are too young to be socialised they demonstrate different interests and aptitudes. This becomes increasingly obvious with maturity.
'Gender feminism' tries to pretend that this is not so. Therefore any differences must be a result of male privilege. This is at variance from 'equity feminism' that acknowledges the differences and rightly demands equality of opportunity.
Your thinking is very black-and-white.
