To Train Up a Child. I have never found anything else (and I read smutfic, fanfic, smut, gore-gasm, etc. but that awful instruction manual of how to completely abuse (both physical and psychological /emotional; everything from advocating hitting your literal days old baby with a plastic ruler or flexible tubing, to gaslighting, manipulation, slut-shaming, victim-blaming, forcing forgiveness of abusers, and sexually repressing them to the point they’ll likely have to see a sex therapist before becoming intimate—even with their spouse after marriage) your child from literally the minute they come home from the hospital. It should be piled up and lit aflame, with the awful authors tied to a stake in the center. But otherwise, I don’t believe in banning, censorship, or book-burnings. But that awful book triggered in me some major flashbacks, and genuinely horrified me to the degree I genuinely believe it should not be allowed to be sold until relabeled as either fiction, true crime, or How Not to Treat Your Children.
