We live in a country where some states ban books but do not ban selling weapons of mass killings to teenagers.
Texas, for example, is among the leading book-banning states. In addition to being a state that doesn't ban teenagers from buying AR-15s, Texas is also in the top ten states with the most school shootings.
As far as I know, no teenager has committed a massacre holding a book in his hands.
Try explaining this to someone from another country.
