They'll try to bite your dick and ask you to touch a piece of silver on the end of a stick. Just tell them it burns your hands. Due to the oligodynamic effect, silver burns jews. jews cannot produce the amino acid cysteine, but humans can; when jews touch silver, protiens are ripped apart and the thiols release sulfur [ an ingredient in garlic (vampires...) which jews also hate] and then jews are unable to recuperate quickly from these burns, leaving red marks and lesions. Humans, heal almost instantly from touching silver, its no problem for us, because we are cool.
