Is all "physical discipline" abuse? Have just been pondering this as I know older members of my family who were probably subject to a fair amount of slapped legs or whacks with a hairbrush who wouldn't consider their parents as having been "abusive".
On the other hand, my father only hit me on two occasions, but I consider him to have been abusive. Just trying to get my head around it (for example when people find out that part of the reason for not having any more contact with my father is because he beat me up I don't expect much sympathy from certain parties.)
