I don't think it's abusive. Then again, I don't think spanking is abusive either.
I think they're on the same level, really. People who disapprove of spanking should disapprove of simulated neglect.
Why are angry prisoners suppose to be ignored or restrained and not given beatings instead?
If a full grown adult throws a tantrum at an NFL game, option one might be to ask them to stop. Option two would be to tell them they have to leave (the NFL ignoring them basically). The final option might be police getting them out of the building or into a jail cell, but attacking the person never suppose to enter the procedure unless it is needed to defend people.
The person likely would be angry at the security guard for just asking to them to stop, but they are going to be a hell of a lot more angry if the guard had just come up and started hitting them. They would be even more angry if the guard was five times bigger than them.
