The most famous forms of Holocaust denial and revisionism tend to focus on Jews, casting doubt, for example, on how many were exterminated in the camps. But denying the impact the Nazis had on the other groups they targeted, including queer and trans people, disabled people and Romani people, is still Holocaust denial. Maybe someone should tell J.K. Rowling.
The reason traditional gender roles are called than and are that is because most people act in accordance with them.
And I disagree that all female characters have less depth intentionally.
These are still books about a boy, told from his point of view. Most of the depth is in his head.
