No analogy between women who are harassed and sexually assaulted by men and two children who have a conflict.  Author is generalizing the unfortunate events in the world to the interactions between children.  Older child (no gender assigned) may in fact be bitten by younger child (no gender assigned), because younger child may not have words and skills to resolve situation.  If older child (no gender assigned), did, in fact, bite, take toy, or any other inappropriate action, he or she needs to understand that there are unfortunate consequences.  Older child does not get a "free pass" because she is a female.  That is reverse discrimination. Dad would probably have said the same thing if the older was a boy and the younger was a girl.  Wrap your head around that.
