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
Plenty show vampires being sophisticated among themselves as well.
Highly recommend reading/watching Interview With The Vampire. The recent TV show was excellent.
A parasite has a long-term abusive relationship with the organism they feed from, much like Thiel. Vampires don't.
Please stop with the anti-vampire propaganda.
