It is not humanly possible to say anything bad enough about zionists that would constitute libel because literally any accusation made toward them would be an incomplete description of the magnitude of evil that they have wrought on humanity.
Besides that, the core accusation that there is a demonic faction within Jewish people who do perverse things to children can’t simply be dismissed without examination because the accused find its publicity uncomfortable. It is not uncommon for criminals to want to hide their crimes because they fear that having a criminal reputation will impede future crimes. The solution is not to exempt such cases from examination, but rather, to examine them all the more closely.
Did you see the recent news stories about the tunnels at the NYC Chabad-Lubavitch (“Israel” supporters incidentally) headquarters?

Instead of investigating why there were soiled child-sized mattresses under a school for allegedly Jewish education, someone at the police department got the brilliant idea that the best way to protect evidence at the crime scene was to immediately fill the tunnels with concrete. Were they engaged in child trafficking? Were they engaged in some perverse se xual exploitation of children? THIS is why “blood libel”…to the extent that it isn’t pure fantasy of whining zionists…exists. The failure to investigate and prosecute CAUSES even more suspicion.
