Lets get one thing straight off the hop. This post is refers to corporal punishment by a parent that does not exceed their parental rights according to the laws of the land where I reside.
Corporal Punishment is still allowed in Canada and parents are protected under the Criminal Code as long as the child isn't "physically injured". There is a current debate going on to see if that should be removed. Currently there are about 40 Countries that have banned it. Of course with any debate there is evidence and opinions for both sides.
Although I never used it, my parents did minimally and I would never in a million years label them or anyone else that used it to such a minimal extent as "abusers", that is not only my own opinion, but the Courts here in Canada agree with it as well.
For my own family it was alternatives such as positive reinforcement to change the behavior, or "time outs", removing our child from the situation. For example if our child had a tantrum or a meltdown in a public place, Grocery Store, Restaurant etc., they would get the three count to settle down or we would pick them up and remove them so we wouldn't disturb other people. We would then go out to the car and sit together until they calmed down. Sometimes it was after a few minutes and we would return, sometimes we wouldn't return at all.
Personally it drives me nuts when in a public place a mom or dad is trying to negotiate a truce for a half hour with a four year old having a meltdown. All that shows me is that the tail is wagging the dog.
I have no doubt that there were and are parents that labelled me or would label me as an "abuser" when I was carrying my screaming 4 year old out of the grocery store to the car....those would be the parents that believe you can negotiate with a screaming child during a temper tantrum meltdown at your favorite restaurant.
For these very reasons people should be cautious with handing out labels. Personal opinions are just that because as
@Marinna noted we aren't there yet legally or culturally when it comes to the "minimal" use of Corporal Punshment and there are those that would even consider other forms of behavior modification, such as mine as being "abuse".
Personally I reserve labels for those that exceed their parental authority.
Just my humble opinion.
