A description of someones actions as being “Blood Libel” is not directed AT Jewish people, it is directed at anti-Semites who are engaged in falsely blaming Jewish people as a group for a nonexistent crime.
SO “Blood libel” has almost always been directed, not at Jewish people, but at ANTI-SEMITES.
Any other glaring inadequacies in your knowledge you need for me to clear up for you?
"Blood Libel - The blood libel is a false accusation that Jews sacrifice Christian children either to use the blood for various "medicinal" purposes or to prepare Passover Matzoth (unleavened bread) or for vengeance and mock crucifixions. It is one of the central fables of Anti-Semitism".
The ADL site offers similar definitions.
Yet you say that the exact opposite is true, that blood libel is a term to describe anti-semites....I just don't know whom to believe, Jewish historians or some anonymous internet knuckle-dragger...decisions, decisions.
