Really real vampire doctors?

There are bad stories, and then there are bad stories that refute their very first sentence within paragraphs.

For example: this article about “self-identified vampires” who have formed their own subculture. The opening line states that these vampires are “doctors … by day.”

However, these particular vampires differ from the vampires at your local Hot Topic because they believe that they suffer from “an internal lack of energy that makes them seek energy from external sources such as the high that comes from the crowd at a rock concert or from the blood of a willing donor.”

So, the author, Laura Zuckerman, is claiming that there are doctorsmedical professionals–who consensually drink the blood of others because they think it provides energy they lack?

Perhaps these doctors are “self-identified” as well.
