I believe that some parents feel that if they have to resort to giving the child a spanking that they have failed to properly train the child, or, that they have some sort of demon child on their hands. Never spank out of anger. This may sound really strange to some, because typically people equate spanking with a frustrated parent who is at the end of their emotional rope. People who spank out of anger often have the wrong motivation. These parents are concerned about what their children do, but they are often more concerned about the public image of the family name, perhaps wanting to appear to be the perfect family.
Parents start spanking out of anger, because they have lost sight of what it means to be a parent.
Children will misbehave and often at the most inconvenient times and places. Remember the overall picture. Simple things such as learning to wait, being patient, taking your turn, sharing, sitting still, being quiet, entertaining themselves, thinking of others instead of themselves, respecting the things that belong to other people, etc will make the difference between whether they are happy or unhappy adults, have a good or miserable marriage, enjoy or resent what they do for a living, and so on. One of the overall goals of discipline is to help children shift from extrinsic discipline, or control, to intrinsic discipline. Extrinsic motivation and discipline come from outside the children from parents, teachers, and other authority figures.
