Yeah, this is a weird one because two people can quote Gygax on this and one of them can say, "Look clearly Gygax said damage that causes hit point loss inflicts wounds" and the other can say, "Look clearly Gygax said hit point loss doesn't inflict wounds". I don't understand how people can draw two different conclusions when obviously Gygax said that at least a good percentage of damage is intuitively damage to the flesh and healing is intuitively healing those wounds. But, yeah, this argument has been done to death.
