And, technically, yes the author is lying. Or actually, abusing quotes to bolster his story a bit. He states, "Aware of these charges, Laurence Gardner and Nicholas de Vere have tried to clear the record. They've acknowledged that vampirism does take place at their rituals, but maintain that they only drink the blood of their own family members, who participate willingly.". Then he goes on to quote some unverifiable stuff from de Vere but in the need to have a quote from Gardner, he takes a quote from a Nexus magazine lecture by Gardner, completely out of context and not even addressing accusations of blood drinking, and slaps it in the middle of it all. As if that was in defense! The Dagobert's revenge article states: "The orthodox establishment's fear of Dracula," writes, Gardner, "was not his treatment of enemies but his in-depth knowledge of alchemy, kingship and the ancient Star Fire customs."
If that isn't the abuse of quotes and...yes, lying, I don't know what is.
Check it out for yourself:
Just search for the latter half of the quote and you'll see it. Exact words. ;) And certainly not in trying to clear any record as the Dagobert's Revenge article would have the reader believe.
As for de Vere, find me a good source because I certainly looked for myself. Supposedly, he had a website once in regards to all this but I wasn't able to find such a website. Went to the dragoncourt website and not much there at all. Did some scouting around and found a large e-book on the origins of vampirism that was supposedly accreditted to de Vere. Some of the quotes used in the Dagobert's Revenge article are also taken out of context from this e-book as well.
Origins of Vampirism
Haven't gone through it in its entirety yet but I still haven't seen anything where de Vere says that he spends his afternoons sipping blood by the seaside. I'll let you know if I find something.
