Ridiculous. The association of the term “blood libel” with the dawn of anti-Semitism in Europe is so well established as to be undeniable by any serious historian. That cannot be changed by googling the term and trumping up a silly counter-argument whereby Christians become the poor victims. To present such an ahistorical and offensive argument is borderline anti-Semitic itself.
The phrase blood libel is not owned by any religion, sect or race. It was applied to the Romans, the Greeks, and Christians alike.
The notion that the use of the phrase is anti-Semitic is insane as is the notion that applying it to the Romans of the second century AD is anti-Semitic.
