Why do you think some cultures try to force children to be right-handed? Do you think this is a good idea or not? Why?

I think some cultures force children to be right-handed, because people are used to using right hand. Or, maybe left-handedness is not allowed in some places. I don't think it is a good idea to force children to be right-handed, because some children are used to being left-handed.Children can choose to be right-handed or left-handed.
