Rape is normal. And it’s also normal for people to kill someone they are mad at. Stealing is normal too. There’re a lot of perfectly normal things that are very destructive to other individuals and to society.
That’s why we invented this little thing called law. But law wasn’t always around keeping an eye on us, so we also invented this thing called morality. It’s sorta a set of rules that everyone should follow, both for their own good and the good of society. When people follow this moral code other people see them as being good people and they gain status in society.
But when someone does something that is normal but also against one of the rules they loose status in society and society might decide to protect itself (which is also normal) from these unruly people by locking them in a small room called a prison.
And once in this prison the rapist may meet a man we all affectionately refer to as Bubba. I’m told that homosexuality is normal too. According to reputation though, Bubba isn’t normal in one respect, unless Bubba’s a horse.
The prison guards should be assured that our perfectly normal rapist is just doing what comes naturally when he screams in pain as his sphincter rips wide open.
Maybe your daughter should explain it like that to the displaced commie professor. While she’s at it have her explain that men who care about rape victims often feel great anger and rage. And that it’s normal for us to want to beat the shit out of anyone who suggests rape is in any way acceptable. Cause rape might be normal, but it’s ain’t acceptable.
