Symbolic warfare is most successful when evoking deep-seated feelings of disgust and arousing fears of contagious impurity.
Anti-Semitism goes beyond perpetuating tropes when it equates Jews with impurity. Impurity is symbolically contagious in many cultural contexts, including that of Nazism and Islam. Impurity signifies the other and is experienced both physically and spiritually as a mysterious and harmful substance of the outside world that keeps attacking, contaminating, defiling and desacralizing the sacred world of true believers. True believers have to protect themselves and their communities against this threat of defilement and to get rid of it once the contamination has taken place. Individuals have to cleanse themselves by means of various purification rites and cathartic practices, while communities cleanse themselves by excluding, expelling, or proscribing the things and people whose presence defiles the community. Those unclean things are Jews, Christians, Trump and Israel supporters.
Anti-Semitic symbolic warfare is flourishing. Once the trope, cartoon, image or conspiracy theory is injected into the internet, apologies only serve to spread the propaganda further. Anti-Semitism is the real highly contagious virus and U.S. Congresswomen, their democrat apologists and propaganda arms like the New York Times are all carriers of the disease.
