Although vampires are recognized to be deadly creatures and their existence is controversial, evidence substantiates that they do indeed exist. The teachings and the records of the past give enough proof for sane people.
Horrible things happen today, due to vampire activity.
Ignoring the problem only increases its severity. The number of vampires is probably multiplying. Vampires would most likely one day rise against humanity, to avenge their long dead ancestors, and turn the human population into a vampire one. People need to be aware of the problem, and educated about vampires, maybe even taught about them in school, so that humans can destroy the legions of the undead and live in peace. If the issue of vampires' existence is to be discussed, then the exact meaning of the word vampire should be clarified.
