Vampire "wannabes". Opinions?

[Xenophon]

Yes but what is the difference.

Moral difference or physical? And how would the difference bear on the matter of ideology? In either case---energy or blood-vampirism---the vampire is roughly in the position of Thrasymachus; his critic, that of Socrates. The former claims his can make better use of your energy than do you. Which position is found in a great many guises in the political bestiary even and especially today, left and right.
