If you really linked the two, you need HELP.
The book is not for kids in any way and it’s clear to most people. Time to recalibrate your humor detector.
Nobody reading this book is abusing their children, that’s just plain a ridiculous thing to say and let’s not even get into the idiocy of comparing it to the copy and paste freak. They’re venting a little frustration, child rearing isn’t all fun days in the park, sometimes they’re a big pain in the @$$. As a friend of mine often said (when his kid was being a pain) “you know why humans have an instinct against killing cute things? protects our young”. It’s not like they’re actually saying this stuff to the kids.
Good grief. That's ridiculous.
This is not a children's book anymore than South Park is a children's cartoon. It is aimed for adults. As a parent, I found it funny. Would I read it to my children? Of course not.
