Looking at the Wiki article linked earlier on this page (from 70's to present), it seems like the number of "men" victims is about equivalent to the number of "women" victims.
There doesn't seem to be a significant statistical difference until you compare "children" to either "men" or "women".
So with an equal number of men v women victims, it doesn't seem to make sense to claim men being under represented, or women being over represented; and therefore doesn't seem to make any sense to argue if cougars can make tell the difference between males v females.
(Not being argumentative... I just feel like I'm missing something since the list of victims doesn't seem to match what everyone is talking about).
