A few months back I was in a grocery store aisle when a mother gave her son a swat on the behind after he started acting up. Some busybody came right up to her and said "that's child abuse!" and stormed off. When I passed her on the way to the next aisle, I said "thank you, you're doing your boy a favor", and she smiled. Farking liberals.
My wife was terrified of this, so... One day when I was out by myself grocery shopping with the kids, I gave one a swat on the bum. Fortunately, no one complained. But once they knew that they wouldn't be treated any differently in public, they never acted up again.
