As a member of a prominent Transylvanian family, I am appalled, and profoundly offended, by the idea of someone even as much as suspecting Peter Thiel could be a vampire. He might be an evil bloodsucking parasite, but he lacks the sophistication mortals have come to associate with vampires over the centuries. It's shocking, really, that some people might confuse him with one.
Vampires are parasites. They're only as polite as they need to be to extract resources from potential hosts. The facade of sophistication only lasts as long as it needs to
Which is ironic, given his recent preoccupation with the Antichrist, as the vampire is an antichrist archetype. Christ gives his blood so that others may live; the vampire takes the blood of others so that he may live.
