As someone who's been spanked as a kid, I think that in a very limited number of situations, spanking is actually OK. It has to be rare enough to have significance when it happens. For instance, only in situations when the child endangers himself or others, like climbing onto a slippery kitchen counter, throwing glass objects around the room, or when a tantrum is clearly a manipulative act and not an innocent meltdown. If spanking happens too often, it its significance gets "diluted", and it becomes, in the child's mind, "just another thing my parents like to do to me". This is especially true with aspie children, who, like myself, will start associating punishments with their parents' free will, and not with their own actions.
