^ I was not making assumptions about what your opinions were on. I was simply stating what I have seen over the internet with the argument that you posted has been used many times, and is a fairly common misconception among'st those who really do not know much about how the myth of vampires came about, and that they are actually based off of historical individuals.
However, I will say that I do know that the Vampiric myth goes back to possibly the stone ages, but it was Bram Stoker's Dracula which really caused the Vampire Lour to take off. And the fact that the story was based off of two of Europe's most blood thirsty individuals is where the modern vampire originates from. You know, there is a reason why the European vampire mythology is remembered by pretty much the world versus those from Africa, the Americas, Asia, Asia Minor, the Middle East, extc. And from what I have seen in Skyrim, the Vampire lore that is present is from the European lore predominantly.
