Every once in awhile someone asks me why I am such a strong Israelphile and why I frequently raise the issue of anti-Semitism here on the blog. Things like this are one reason. From the article quoted there,
In another stage of the Passover celebrations, [the Jews] combined the preparation of matzas and the offering up of sacrifices with their enmity towards non-Jews, especially Christians, and mixed the blood of one of their victims into the matza [dough. This was done] especially on Passover, Purim and circumcision rituals. They also used blood in acts of sorcery and witchcraft...
...The draining of the victims' blood is done in [several ways. One method is] by means of a barrel lined with needles. This is a barrel the size of the victim's body, with sharp needles that stick into all his limbs when he is placed in it, so that his blood slowly trickles down from every part of his body. This entails excruciating torment, which gives pleasure to the Jews who become drunk with joy at the sight of the blood dripping from the victim's [body] to the bottom of the barrel and into a container placed there to collect it. [Another method] is to slaughter the victim like a sheep and collecting his blood in a vessel, or else slashing the victim's veins in numerous places so that the blood flows from the wounds into the vessels. Then the blood is handed to a rabbi who prepares a matza laced with human blood in order to please the Jewish god, Jehovah, who thirsts for blood. The Jews can rejoice in their holidays only if they eat matza laced with the blood of non-Jews. [emphasis added]
I once had a friend tell me all about the Protocols of the Elders of Zion as if that fabrication was factual. So I did some internet searches, discovered it was a fraud, printed off the results, and took them to him. His wife looked at him critically then as if to say, "See, I told you so."
