That said, people who refuse to discipline their kids not only influct their unruliness on society, but actually hate them. Look it up in Proverbs. Proverbs 13:24 (KJV) He that spareth his rod hateth his son: but he that loveth him chasteneth him betimes (promptly, diligently). Proverbs 19:18 (KJV) Chasten thy son while there is hope, and let not thy soul spare for his crying.
And here all this time I thought the “Spare the rod, spoil the child” saying was an admonition against artificial insemination. :=)
Today someone would spy you spanking your child in the parking lot and call 911. You would have child protection after you. The world has changed a lot.
