You said it yourself: they're pseudo-intellectuals. And they are definitely having trouble separating fantasy from reality. I wonder if it has something to do with an inferiority complex at it's heart. They lose the ability to separate reality from fantasy, have some self-esteem problems and find something in all of this supernatural fantasy stuff that enables them to have some confidence and so they latch onto it and it just snowballs after that. At that point, it becomes a self-feeding ego-trip where they convince themselves more and more that they are special and better than everyone else. Doesn't help when one of them gets some media attention like this Don Henrie guy, either, because it just reinforces it for them and gives them a medium to draw in other folks who are lacking something in their lives that they get the idea being a "real vampire" can fill in for them.
