The irony is that the "antisemitism" accusation now really serves to hide actual "antisemitism". Similar to how the accusation of "racist" is now bandied about by useful idiots whenever another does not go along with the latest craziness on the Satanic agenda.
Antisemitism once meant to be opposed to one just because that one was of Semitic origin (i.e. race), but in recent decades, has been used to silence all dissent and disagreement if the other claims to be of Jewish race or religion. For example, the claim that George Soros is an evil man is not anti-semitism, for the sole reason that George identifies with the Jewish race or religion. The claim that the Zionist state has engaged in illegal activities or crimes against humanity is not anti-semitism, simply because its leadership claims to be a Jewish state. A claim is never anti-semitism if it is true, and sometimes, is not anti-semitism even if it is false (dependent on the reasons for the error).
