It's pretty pathetic watching this one christkike samefag all over this thread. Even though it's usually pointless to try and educate a cultist of the tortured one, I'll share some info counter to his blathering.
1. The cross as a holy symbol predates the birth of rabbi Jeshuah by about 3,000 years at least. It has been found on pottery, weapons, and of course in jewelry going back into the stone age. It is a symbol of the undying sun. Not only did the judeo-greeks who subverted this symbol steal the idea of the cross representing eternal life, but they very characteristically belittled it by warping it's shape to resemble the torture device used to murder the mortal man they made a human sacrifice and then deified in an image of eternal agony.
2. The vampire ALSO predates the cult of the tortured one. Pretty much every culture around the world and for time immemorial has feared and warded against specifically a risen corpse that consumes life essence, be it lifeblood or your very soul. The Romans buried plague victims with stones in their mouths so they did not return as a strix that would take the form of a black bird and suck the blood of babies. The Romanian strigoi, from which the modern vampires originates, evolved from this word. The Babylonian Lilitu was a spirit of those not properly buried or who died in agony. It was the direct inspiration for the jewish myth of Lilith in the old testament.
3. The idea that the warped cross would repel a vampiric creature because they are somehow the opposite of Jeshuah is absurd for reasons even beyond the above stated. I think demonic life eating entities would love the warped cross because the cult it represents is the only one in the world that requires it's adherents to gather once a week to DRINK THE BLOOD AND EAT THE FLESH OF AN INOCCENT VICTIM TO ABSORB HIS LIFE ESSENCE AND LIVE FOREVER.

Bonus point: Most cultures agree that the only way to stop a vampiric entity is to bury it again with prejudice.
