In the same vein, forced encounters with unwelcome sexually explicit material constitutes intellectual rape
Intellectual rape isn’t a thing. I can’t find any literature or sources right now that debate these exact same words. Also
rape is a physical violent action.
It is severely concerning that you are using these words about reading a book. Others have asked the same question, as to, why you don’t try to sit with her and work through it?
She will not get far at university by claiming that uncomfortable topics and literature are
raping her intellectually.
Science also says that open conversations about sex, consent, violence, and boundaries—discussed age appropriately—help children and youth understand their own boundaries in those topics. Reading material that makes her uncomfortable, and dealing with it, as maturely as possible would be the best outcome.
Instead, it feels like you are trying to advocate shielding her from anything that she finds morally reprehensible.
We are to live in this world, and not in a cocoon, shielded from the world.
