The blood drinking and baby eating (Get in my BELLY!) accusation is sort of amusing from where I sit, because it is the typical (trademarked if you will) accusation against any group that is disliked, and has been for millenia. The Hellenes accused the Persians of this, who accused the Hellenes right back. The Romans accused the Jews and Christians of this, while the Jews and Christians accused the Romans of the same. The common denominator in descriptions of heretical rituals in most inquisition records include descriptions of infanticide and infantophagy. Of course not only heretics indulged in this behaviour, Jews and Muslims were accused of the same thing, and the Muslims (of course) swore the Christians did this (with some measure of validity, think about what your opinion of the Eucharist might be if you had only third or fourth hand information...). Catholics accused Protestants of munching on munchkins, as did Protestants (see some of the broadsheets produced as Catholic and Protestant propoganda in 16th and 17th centruy Europe.). In WWI and II the Germans and (WWII) the Japanese were portrayed as baby killers (The "Why We Fight" series of 'informational newsreels' dealing with Japan frequently showed shots of an orphanage in Manchuria that had been bombed. I read somewhere that it had actually been bombed by the US, but that bit was conveniently ignored.).
In an era where the existence and actions of Israel are so explosive a topic, I am unsurprised that the "blood libel" is back. It is sort of boring, why can't we have a new myth? I know, the Jews are aliens, who actually built the face on mars, and Sharon in a Cylon!
P.S. : The Battlestar Galactica comment reminded me that the LDS church was also accused of infantophagy in the 1880s. Sigh!
