A pale, slender, elegant woman of elven heritage dressed in flowing white robes approaches and studies the string of messages...
The right to life, or unlife as the case might be? There is no such thing...
What right to life has the man who is drowning in the middle of the ocean? The sea will not hearken to his cries. To live is not a right; it is a privilege won by sheer effort, or granted by those who make sacrifices to insure the safety of their fellows.
Personally, I despise vampires and agree that the predatory leeches ought to be exterminated, as one would dispose of rabid dogs that pose a threat to innocent folk. However, many of those who claim to be vampires are nothing more than mentally disturbed individuals with a vampire fetish. They are not really vampires, they only think that they are vampires. (This explains why they can roam about in the sunlight, are unaffected by holy water, and so forth...)
In my estimation, the world would be better off without these delusional mock-vamps, too. Stake them all, to your heart's content.
