Uh, what?
Adding stimulae isn't de facto preferable to the removal of them. I strongly dispute your assertion that physical punishment is a form of "positive punishment", which is a nonsense term in a league of its own.
He's using psychology positive reinforcement vs negative reinforcement vs positive punishment vs negative punishment.
Positive means doing or giving something.
Negative means removal or not doing something.
Regardless, what he said is in line with the status quo: Wifes have rights, but children do not.
