Moderate corporal punishment of children has been acceptable in the Occident since forever

Go back to Rome and immoderate punishment by the paterfamilias or at his order, up to and including execution, was allowed.

The liberals freed us from legal enforcement of Christian morals only to subject us to legal enforcement of their own.

Not always an improvement.
