Let me first make clear that the Social Psych definition of "aggressive behavior" (which carries over to both Sociology and Psychology) is "any behavior (whether by commission or omission, action or inaction, speech or silence) that is intended to injure another person who does not want to be injured."  Of course, this includes violence (with the exception being athletic violence within the rules of a given sport).

The fact of the matter is that, while there is a correlational link between pornography and aggressive behavior, there is no causal link.  In other words, porn isn't going to cause you to be violent, or otherwise aggressive, toward women unless you are already predisposed toward aggressive behavior in general.  (There is an exception in the case of "rape porn," but that is a whole different discussion.)
