Incestuous infatuation? More likely, this was a guy who took the kind of semi-joke in
post #12 here more literally than most FReepers do. But just consider why that "Dating My Daughter" survey has been posted on this forum dozens of times (and probably posted thousands of times elsewhere). Many fathers do feel inclined to violence at the thought of daughters under their roof (and therefore under their protection) getting sexually involved. Too bad for the kid that he didn't realize he was dealing with one of them.
I just don’t understand why any normal father should be any more obsessed with his daughter’s sex life as opposed to his son’s. The only thing that occurs to me is that she is a reflection of her mother and somehow he has displaced sexual yearnings for his mate onto his child. At any rate such an obsession is sick in my opinion.
